Add the polynomials.
(2x² + 9x - 8) + (4x2+2x-2)
The sum is __ ?

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

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
