Question

1. $(8p - 2)(p + 1)(2p)$
2. the perimeter of an isosceles

Explanation:

Step1: Multiply first two binomials

$$(8p-2)(p+1) = 8p(p+1) - 2(p+1) = 8p^2 + 8p - 2p - 2 = 8p^2 + 6p - 2$$

Step2: Multiply by the monomial $2p$

$$(8p^2 + 6p - 2)(2p) = 8p^2(2p) + 6p(2p) - 2(2p)$$

Step3: Simplify each term

$$= 16p^3 + 12p^2 - 4p$$

Answer:

$16p^3 + 12p^2 - 4p$
