(-28-32r-x+ 1)(x-2) multiply and combine like terms to determine product of polynomials.​

−25x+54−32rx+64r−x^2

Step-by-step explanation:

(−28−32r−x+1)(x−2)

Add −28 and 1 to get −27.

(−27−32r−x)(x−2)

Apply the distributive property by multiplying each term of −27−32r−x by each term of x−2.

−27x+54−32rx+64r−x^2+2x

Combine −27x and 2x to get −25x.

−25x+54−32rx+64r−x^2

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
