Question

Find p(2a+8) for the polynomial p(x)=−5x−4.

a)p(2a+8)=−10a+44

b)p(2a+8)=10a−44

c)p(2a+8)=−10a−44

d)p(2a+8)=10a+44

Answer 1

To find p(2a+8) for the polynomial p(x)=-5x-4, substitute 2a+8 in place of x in the polynomial and simplify the expression.

Step-by-step explanation:

The following is from the topic solving polynomials and finding the value of x by simplifying the expression.

To find p(2a+8) for the polynomial p(x)=-5x-4, we substitute 2a+8 in place of x in the polynomial:

p(2a+8) = -5(2a+8) - 4

Expanding and simplifying the expression, we get:

p(2a+8) = -10a - 40 - 4

p(2a+8) = -10a - 44

So, the correct answer is option A: p(2a+8) = -10a - 44.
