Answer:
Ok so first you want to distribute the -1 in front of the 3x^2-7x+1
Which turns the problem into
X^2+5x-6 -3x^2+7x-1
Then just combine like terms
-2x^2+12x-7
Also ^ followed by the number is the exponent

Answer:
27 Degrees
Step-by-step explanation:
Since 63 and x make 90 degrees, 90-63 is 27 which gives you the answer. The equation is X=90-63.
Answer:
63 + x = 90
Step-by-step explanation:
The desired equation is 63 + x = 90, because the angles 63 and x are complementary (they add up to 90 degrees).
What is the formula for the volume of a trapezoidal prism?
Answers
Answer:
Ok so basically, the formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2. In other words, multiply together the length, height, and average of A and B.

Parallelogram 3 length: 20 in. width: 21 in. diagonal: 29 in. Parallelogram 4 length: 18 in. width: 20 in. diagonal: 26 in. James put the parallelograms together so one vertex from each paper exists on a point, as shown in the circle. 4 parallelograms are put together so that one vertex from each paper exists on a point. Which statement explains whether or not the parallelgrams can be put together so each occupies one-quarter of the area of the circle without overlapping any other pieces? Check all that apply. The quadrilaterals can be placed such that each occupies one-quarter of the circle. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 1 do not form right angles. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 2 do not form right angles. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 3 do not form right angles. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 4 do not form right angles.

Step-by-step explanation:

Answer:
The degree of this polynomial is 3.
Step-by-step explanation:
Hey!
==================================================================
When a polynomial has more than one variable, we need to look at each term to find out what the degree is. Terms are separated by + or - signs.
Find the degree by adding the exponents of each variable in it,
The largest such degree is the degree of the polynomial.
Let's start out by finding the degrees for each terms:
3x³ = The degree, or exponent, of x is 3.
5x² = The degree, or exponent, of x is 2.
1 = Constant Terms do not have a degree.
So, since the largest degree of a term is the degree of the polynomial., The degree of this polynomial is 3, since that is the highest!

Step-by-step explanation:
Answer:
18 1/12 ft = base length
Step-by-step explanation:
The area of a triangle of base b and height h is A = (1/2)(b)(h).
Since we want the measure of the base we solve this formula for b:
2A = (b)(h)
2A
and then divide both sides to obtain a formula for b: b = -----------
h
Substituting 217 ft^2 for A and 24 ft for h, we get:
b = 2*217 ft^2 / 24 ft = 18.0833.... ft
If the answer must contain a fraction, take the 18 and hold it and convert the remaining 0.08333... to a fraction. One way of doing this is to use a calculator. On my old TI calculator, I would type in 0.0833333333..
and then press the MATH key and then select Option 1: Decimal to fraction.
Doing this yields 1/12. You can check this result by dividing: 1/12 = 0.08333...
Then the final answer, converted from 18.08333... ft, is
18 1/12 ft = base length

2) 52 Explanation: 45 divided by 9 is 5 then 5 times 12 gives you 60. equation now is 60-8 which equals 52.

4) 89
5)111
6)72
Answer:
1. 145-(3squared times 4)=109
2. 45 divided by 9 times 12-8= 52
3. 2 squared +3 times 4-12= 4
4.[155-(3 times 9) times 2] -12= 89
5. [(6 times 2) +(5 times 5) times 3= 111
6. 2 times {15+[24-(1.5 times 2)]}= 72
Step-by-step explanation:
(BOMDAS) brackets, operations, multiplication, division, addition, subtraction
1. (deal with the brackets first)
3 squared=9 then times by 4 =9*4=36
so..
145-36=109
2. (start with division )
45 divided by 9 =5
so
5 times 12-8= 52
3. 2 squared = 4
4 times 3 =12
so
4+12-12 =4
4. (deal with brackets first)
3 times 9 = 27
27 times 2= 54
155-54= 101
101-12=89
5. (deal with the brackets first)
6 times 2 =12
5 times 5=25
so 12+25= 37 times 3 = 111
6. (deal with the brackets first)
1.5 times 2= 3
24-3= 21
15+21=36
2 times 36= 72

What is the surface area of the triangular prism below?
Answers
Answer:
Let me figure it out rq hold on
how to find the surface area:
The surface area of the triangular prism is the sum total of the areas of its bases and its lateral faces,
We have 2 triangles to add and 3 rectangles.
Area of a rectangle is length x width.
Area of a triangle is 1/2 x base x height.
The top 2 rectangular sides are 20 x 10 = 200 each = 400 total.
The bottom rectangle is 20 x 12 = 240
The triangles are each 1/2 x 12 x 8 = 48, and there are 2 triangles, = 96
Add them all up: 400 + 240 + 96 = 736 square feet

Answers
Answer:
l = 14
Step-by-step explanation:
The perimeter of a rectangle is
P =2(l+w)
The width is x-6
w = x-6
The length is 8 units longer than the width
l = w+8
l = x-6+8
l = x+2
We can substitute this into the equation for Perimeter, which is given as 40
40 = 2(x+2 + x-6)
Combine like terms
40 =2 (2x-4)
Divide by 2
40/2 = 2/2 (2x-4)
20 = 2x-4
Add 4 to each side
20+4 =2x-4+4
24 = 2x
Divide by 2
24/2 =2x/2
12=x
We want to know the length
l = x+2
l =12+2

Answer:
144 ft^2
Step-by-step explanation:
Here we have a trapezoid with a triangle inside.
The legs of the trapezoid are 18 ft and 8 ft, and so the average length of the trapezoid is (18 + 8)/2 ft, o 13 ft. The total area of the trapezoid is thus:
A = (13 ft)(16 ft) = 208 ft^2
Now we must find the area of the white triangle and subtract it from the area of the trapezoid already found. The area formula for a triangle i
A = (1/2)(base)(height), which in this case is A = (1/2)(8 ft)(16 ft), or
A = 64 ft^2.
Subtracting the area of the triangle from that of the trapezoid yields
Area of figure = 144 ft^2
