The value of x is: 
<u><em>Recall</em></u>:
Perimeter of a shape is the sum of all its sides
<em>Thus</em>:
Perimeter of the triangle = 
Perimeter of the rectangle = 
We are told that the perimeter of both shapes are equal. Set both perimeters equal and solve for x.
<em>Add like terms</em>

Hello from MrBillDoesMath!
Answer:
2 * (Pi r^2) + (Pi r^2)*h
where r = C/(2 Pi)
Discussion:
Total surface area of cylinder =
area of bottoms + surface area of cylinder =
2 * area of base + (area of base) * h
Generally, C = 2 Pi r, so r = C/(2 Pi) is known as we are given C. . Plugging this in the above equation gives
2 * (Pi r^2) + (Pi r^2)*h
Thank you,
MrB

Answer:
The second and third line are wrong
Step-by-step explanation:
(4x³ +4x²-8x) -(8x²-16x+4)
= 4x³ +4x²-8x - 8x²+ 16x -4
= 4x³ +4x²- 8x²-8x+ 16x -4
= 4x³ -4x²+ 8x -4
In the second line:
it has to be +16x because - times - is +
it is like -1*(8x²-16x+4)
In the third line:
you can only add or subtract the xs with the same exponentation, so
4x²- 8x² and -8x+ 16x
4x²- 8x²= -4x² not +12x²
