"if a=2, what is the simplified form of the expression below? (x)(x^2+ax+a^2)"

a=2

expression --->  (x)(x^2+ax+a^2)

               when a =2,  (x)(x^2+2x+2^2)      

                NOW DISTRIBUTE THE x

                      x^3+2x^2+4

hope it helps u mate!!!

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

its 50 miles away from the starting point
