<span> Let h = height. This makes the base h + 17.
h(h + 17)/2 = 55
h(h + 17) = 110
h^2 + 17h = 110
h^2 + 17h - 110 = 0
(h + 22)(h - 5) = 0
h = -22 or h = 5
Discard h = -22 because a negative height makes no sense, leaving just
h = 5in
base = 5 + 17 = 22in</span>
Answer:
cool
Step-by-step explanation:
Wouldn't it be answer b)?
X^3 - x^2 - 2x = 0
x ( x^2 - x - 2 ) = 0
x (x-2) (x+1) = 0
x = 0
x-2 = 0 --> x = 2
x+1 = 0 --> x = -1
x = 0, x = 2, x = -1
