First correct answer gets 10 points!! hurry

Step-by-step explanation:

The area of a parallelogram is b * h, where b is the base and h is the height. We'll call the height x and the base x + 4, and we know that this is equal to 45.

x (x + 4) = 45

x² + 4x = 45

x² + 4x - 45 = 0

(x + 5)(x - 4) = 0

x = -5, 4 → x = 4 (no negative sides)

Therefore, base is 8 and height is 4. Hope this helps!

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
