What is the area of the triangle?
Answer:
Area = 40 sq units
Step-by-step explanation:
Area of a triangle:
A = 1/2•b•h
= 1/2•8•10
= 40 sq units
Expand.
Your answer should be a polynomial in standard form.
(-p? - 4p - 3)(p2 + 2)
Answer: Here is the answer.
Step-by-step explanation: we have to multiply each of the terms with the other terms.
=(-p²+4p-3)(p²+2)
=-p²*p²+ ( -p²*2) + 4p*p² + 4p*2 - 3*p²+ ( -3*2)
= -p³ -2p²+4p³+8p-3p²-6
=3p³-5p²+8p-6 (I grouped the like terms and added them)
therefore, 3p³-5p²+8p-6 is the polynomial in the standard form.
a bakery sold 10 more cakes this month than it did the last month. It also sold 3 times as many cakes in this month than in the month before the last month. If that total number of cakes it sold in the last 3 months is 116, how many cakes did it sell last month?
Answer:
Last month it sold 338 cakes.
Step-by-step explanation:
Let total cakes this month,last month and last 3 months be x,y and z respectively,
x = y + 10...
x = 3z
z = 116
Now, we have to find y,
x = y + 10
or, 3z = y + 10
or, 3•116 = y + 10
or, 348 = y + 10
or, y = 348 - 10
so, y = 338
What is the slope of the line that passes through the points (0, -8)(0,−8) and (0, -10)(0,−10)? Write your answer in simplest form.

The slope of a given line is -2/0.
The given points are (0, -8) and (0, -10).
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
We know that, slope m = (y2-y1)/(x2-x1)
Put (x1, y1) = (0, -8) and (x2, y2)=(0, -10) in slope formula
That is, (-10-(-8))/(0-0)
= -2/0
= not defined
Therefore, the slope of a given line is -2/0.

A circle has a diameter of 21 meters. What is the circumference of the circle? Use 22/7 for ∏.
Answer:
66
Step-by-step explanation:
The diameter of the circle is 21. The formula for circumference is pie*radius*2. We don't have the radius but the diameter is just double the radius so just don't multiply by 2. 21 x 22 = 462. 46s divided by 7 is 66. Enjoy your answer :D
Radhika buys papaya at the rate of p(x) = x² – 12x – 220 per kg
(i) the factors of the given polynomial
(ii) if she purchase 5kg papaya, what money she have to pay?
Answer:
(i) The factors of the given polynomial is (x – 22) and (x + 10)
(ii) If she purchase 5kg papaya then she pays 110
Step-by-step explanation:
Given;p(x) = x² – 12x – 220 per kgTo Find;The factors of the given polynomialif she purchase 5kg papaya, what money she have to pay?(i)Now,
x² – 12x – 220 = 0
Splitting the middle term
x² – 22x + 10x – 220 = 0
x(x – 22) + 10(x – 22) = 0
(x – 22) + (x + 10) = 0
x – 22 = 0 or x + 10= 0
x = 22 or x = -10
Here, (-10) is the negative value hence it is not possible
So, The value of x is 22
The factors of the given polynomial is (x – 22) and (x + 10)
(ii)if she purchase 5kg papaya then,
we know the price of 1 kg papaya i.e., 22 per kg
So,
5 × 22 = 110
Thus, if she purchase 5kg papaya then she pays 110

Question: “How many people are greater than 62 inches tall? “
Can someone please help me kn this :)
Answer:
5
Step-by-step explanation:
Consider the equation - 2x + 3y = 6
Part A: Write the equation in slope-intercept form.
Part B: Identify the y-intercept.
Part C: Identify the slope.
Step-by-step explanation:
Hey there!
The given equation is: - 2x + 3y = 6
Part A:
The slope intercept form equation is: y= mx+c.
So, make the equation in y= mx+c form.
- 2x + 3y = 6
Shift -2x right side;
3y = 6+2x
Divide both sides by 3.
y = (6+2x)/3
y = (2/3)x +2
Therefore, the required equation in slope intercept form is: y = (2/3)x +2.
Part B:
When the equation is in y= mx+c form "c" represents the y-intercept.
So, y-intercept is 2.
Part C:
From the equation y = (2/3)x +2,
The slope (m) = 2/3.

Dave wants to buy 5 games, 10 Funko Pops, and 6 toys. He was $2,614 .If each game is $50, each Funko Pop is $30, and each toy is $40. How much money does Dave have left?
Answer:
$1,824
Step-by-step explanation:
Games Dave wants to buy: 5
Cost of each game: $50
Cost of 5 games = $50 x 5
= $250
Funko pops Dave wants to buy: 10
Cost of each funko pop: $30
Cost of 10 funko pops = $30 x 10
= $300
Toys Dave wants to buy: 6
Cost of each toy: $40
Cost of 6 toys = $40 x 6
= $240
Sum of all Dave's things = ($250 + $300 + $240)
= $790
Money Dave has = $2,614
Money left with him = ($2,614 - $790)
= $1,824
Hence, $1,824 are left with Dave after buying 5 games, 10 Funko pops and 6 toys.
Pls correct me, if I am wrong :)
Have a great day!

Step-by-step explanation:
It basically shows you that based on the inequality sign.
Answer:
x solved is 0 < x
and graphing it on the number line
-1 0 1
O->
Step-by-step explanation:
So, solving for x is easy you divide the 2 from 2x onto the other side and 0/2 is 0 meaning 0 < x, the < stays the same as you divided with a positive and it would start at 0 and the line would go to the right as 0 is less than x. if you have to it would be a open circle with a dotted line if deltamath makes you do that too.

One number is 3 less than 4 times a second number. The difference of the
first number and twice the second number is 7. What are the two numbers?
Show your work.
Answer:
the two numbers are 5 and 17
Step-by-step explanation:
4y - 3 = x
x - 2y = 7
to find y:
x - 2y = 7
(4y - 3) - 2y = 7
2y - 3 = 7
2y = 7 + 3
2y = 10
y = 10/2
y = 5
to find x :
4y - 3 = x
4 ( 5 ) - 3 = x
20 - 3 = x
17 = x

504
Hope This Helps!!!
Answer:
504 sq.in.Step-by-step explanation:
Given,
Edges of a box = 12 in. , 15 in. , 6 in.
So,
Lateral Surface Area (LSA) of the box
= 2 (l + b) h
[On substituting their values]= [2 (12 + 15) × 6 ] [tex]in^{2}[/tex]
[On simplifying]= [2 × 27 × 6] [tex]in^{2}[/tex]
On multiplying]= 324[tex]in^{2}[/tex]
And,
Base area of the box
= l × b
[On substituting the values]= (12 × 15) [tex]in^{2}[/tex]
[On multiplying]= 180 [tex]in^{2}[/tex]
Therefore,
Total area painted by Agnes leaving the top of the box
= LSA of the box + Base area of the box
[On putting their values]= 324[tex]in^{2}[/tex] + 180 [tex]in^{2}[/tex]
[On adding]= 504[tex]in^{2}[/tex]
Hence,
The total area painted is 504[tex]in^{2}[/tex] (Ans)
