Find the area of the triangle that has a base of (p - 8) and a height of (2p - 16).
Hint: draw a picture!
p 2 − 16p − 64
p 2 + 16p + 64
p 2 − 16p − 8
p 2 − 16p + 64
The perimeter of the triangle is
3x3 + 4x2 + 8x + 15. If the shortest side is 2x2 + 12x and the longest side is
x3 – 8x + 7, what is the missing side length?
2x3 + 2x2 + 4x + 8
4x3 + 6x2 + 12x + 22
2x3 + 6x2 + 28x + 8
4x3 + 2x2 - 12x + 22
