The difference between the two polynomials is 11x²3y³ - 4xy².
What is the Difference between the Polynomials?The difference between two polynomials is the result you get by subtracting one from the other.
Thus:
= (4x²2y³ + 2xy² – 2y) – (–7x²y³ + 6xy² – 2y)
= 4x²2y³ + 2xy² – 2y + 7x²y³ - 6xy² + 2y
= 11x²3y³ - 4xy²

Susie needs to cover her triangular garden with new top soil. Her garden has a base of 7 ft and a height of 10 ft. A bag of soil will cover 5 square feet. How many bags will she need?
Question 7 options:
70 bags of soil
35 bags of soil
12 bags of soil
7 bags of soil
If 1 bag of soil will covers 5 square feet, the number of bags of soil that will cover Susie's 35 square feet triangular garden is 7 bags.
Option D) is the correct answer.
How many bags will Susie need?Area of a triangle is expressed as half base multiply by height.
A = (1/2)base × height
Given that;
Base of the triangular garden = 7ftHeight = 10ftArea of the triangular garden A = ?A = (1/2)base × height
A = (1/2) × 7ft × 10ft
Area of the triangular garden A = 35ft²
Now, if 1 bag of soil covers 5 square feet. how many will cover 35 square feet?
1 bag covers 5ft²
x bags covers 35ft²
x = 35 / 5
x = 7 bags
Therefore, if 1 bag of soil will covers 5 square feet, the number of bags of soil that will cover Susie's 35 square feet triangular garden is 7 bags.
Option D) is the correct answer.

[tex]\diamond\large\textsf{\textbf{\underline{Answer and How to solve:-}}}[/tex]
[tex]\it{Volume\:of\:a\:sphere:-}[/tex]
[tex]\longmapsto\sf{V=\dfrac{4}{3} \pi r^3}[/tex]
[tex]\bold{\underline{Where:-}}[/tex]
V=Volumeπ = pi r=radius
Provided information:-
diameter = 10 m
What we need in order to find the Volume:-
radius
How to find the radius if we have the diameter?
Since the radius is exactly one-half of the diameter, we divide the diameter by 2:-
[tex]\bold{r=d\div2}[/tex]
Replace d with 10:-
[tex]\bold{r=10\div2}[/tex]
Therefore, the radius of the sphere is
[tex]\bold{r=5}[/tex][tex]\rule{300}{1}[/tex]
✓ Now we have all the required information in order to find the volume of the sphere.
✳︎Substitute 5 in lieu of r:-
[tex]\bold{V=\dfrac{4}{3} \pi (5)^3}[/tex]
➪On simplification,
[tex]\bold{V=\dfrac{4}{2} \pi (125)}[/tex] ◈ Next, write the value of π (3.14…)
[tex]\bold{V=\dfrac{4}{3}\times3.14\times125}[/tex]
On further simplification,

Which equation represents a linear function?
Answer:
y = x-3
step by step explanation:
The equation of a linear function has no exponents higher than 1
check whether (x-1) is a factor of 2x²-3x+1 or not ................
Answer:
(x - 1) is a factor of 2x² - 3x + 1
Step-by-step explanation:
Method 1
If (x - 1) is a factor of f(x) = 2x² - 3x + 1 then f(1) = 0
Substitute x = 1 into the equations:
f(1) = 2(1)² - 3(1) + 1
= 2 - 3 + 1
= 0
Therefore, (x - 1) is a factor of 2x² - 3x + 1
Method 2
Factor 2x² - 3x + 1
Find 2 two numbers that multiply to 2 and sum to -3: -2 and -1
Rewrite the coefficient of the middle term as the sum of these 2 numbers:
⇒ 2x² - 2x - x + 1
Factorize the first two terms and the last two terms separately:
⇒ 2x(x - 1) - 1(x - 1)
Factor out the common term (x - 1):
⇒ (2x - 1)(x - 1)
Thus proving that (x - 1) is a product of 2x² - 3x + 1
The diameter of a cylindrical construction pipe is 3 ft. If the pipe is 12 ft long,
what is its volume?
Use the value 3.14 for π, and round your answer to the nearest whole
number.
Be sure to include the correct unit in your answer.
Work Shown:
d = 3 = diameter
r = d/2 = 3/2 = 1.5 = radius
h = 12 = height or length of the pipe
pi = 3.14 approximately
V = volume of the cylinder pipe
V = pi*r^2*h
V = 3.14*(1.5)^2*12
V = 84.78
V = 85
The cylindrical pipe's volume is about 85 cubic feet.

Answer:
D. 96 m²
Step-by-step explanation:
The surface area of a triangular prism is the sum of the areas of all of the faces. A triangular prism has two triangular faces (bases) and three rectangular faces.
__
rectangular facesThe dimensions of the rectangular faces are such that they can be considered together as a rectangle whose width is the distance between the triangular faces, and whose length is the perimeter of the triangle. For this prism, that is a 7 m width and a (3+4+5) = 12 m length.
triangular facesThe two triangular faces together have an area that is equal to that of a rectangle with the same base and height as the triangular face. For this prism, that is a 3 m base and a 4 m height.
totalThe total surface area is ...
lateral area + base area = (7 m)(12 m) +(3 m)(4 m) = (84 +12) m²
surface area = 96 m²
_____
Additional comment
The formula for the area of a triangle is ...
A = 1/2bh
A triangular prism has two congruent triangular faces, so their total area is ...
A = 2(1/2bh) = bh
We elected to skip the halving and doubling, and go straight to the total base area.

The probability that you select a comedy to watch second given that you randomly selected a comedy to watch first will be,[tex]\rm \frac{1}{5}[/tex].
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1.
Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

How to determine the error in the steps?When a regular hexagon is to be inscribed in a circle, the first step is to place the compass on the circumference of the circle and create an arc.
On no occasion should the width of the compass equal the diameter of the circle.
The step 1 in the question shows that the compass width is set to the diameter of the circle.
This is wrong, and it needs to be revised.

davion bought a new controller for $32. he also bought a stuffed elephant for his brother. he paid everything with 4 twenty dollar bills.if he got $18 back in change how much did the stuffed animal cost?
Answer:
$30
Step-by-step explanation:
First we will find how much money Davion paid with.
4 * $20 = $80
Now we can find how much the stuffed animal cost using the controller cost and change received.
Let x be the cost of the stuffed animal
80 = 32 + 18 + x
80 = 50 + x | subtract 50 from both sides
30 = x
This means the stuffed animal cost $30.

Answer & Step-by-step explanation:
These questions are wanting you to find the sequence and solve for the nth term in said sequence.
The easiest way to do this is to just see the difference between each number, and continue adding or subtracting to the nth term the question is asking for.
For example, the first one is decreasing by 3 every time, so the 7th term will be -4, (the 4th term), subtracted by 3, three more times.
5, 2, -1, -4, -7, -10, -13
The other way to do this is to find the rule, and subsitute in what term is required.
For letter c (the second c), the sequence is 30, 24, 18, 12
The rule is to subtract 6 every time, so -6 n
Since we start our 1st sequence from 30, our rule must start from 30 + 6, the opposite of our rule, which gives us 36.
Our rule is 36 - 6n
So since we are looking for the 11th term, we substutute in 11 into our equation.
36 - 6 n
36 - 6 (11)
36 - 66
-30

has adopted a second cat, she needs to serve a total of 3 1/2 cans each day. How much extra
food is needed to feed the second cat?
Write your answer as a fraction or as a whole or mixed number.
cans
Based on the information provided, to feed the second cat it is necessary 1 1/2 extra cans or 1.5 cans.
How much extra food is needed to feed the second cat?This difference can be found by substracting the total cans fed with only one cat to the total fed with two cats:
3 1/2 cans - 2 cans = 1 1/2 cans, which can also be expressed as 1.5 cans.Based on this, to have a second cat implies 1.5 extra cans.
