Answer:

Step-by-step explanation:

Given

p² + 2p - 8 = 0 ← in standard form

with a = 1, b = 2, c = - 8

Using the quadratic formula to solve for p

p = ( - 2 ± $\sqrt{2^2-(4(1)(-8))}$ / 2

= ( - 2 ± $\sqrt{4+32}$ / 2

= ( - 2 ± $\sqrt{36}$ ) / 2

p = $\frac{-2-6}{2}$ = $\frac{-8}{2}$ = - 4

p = $\frac{-2+6}{2}$ = $\frac{4}{2}$ = 2

The surface area formula of a trapezoidal prism is h (b + d) + l (a + b + c + d)

4(9+7) + 11 (5+7+9 +5)

--> 350

A(x) = P(1.02)^x
A(x) = P(1 + 0.02)^x
A(x) = P(1 + r)^x

Therefore rate of change = 0.02 = 2%
