Compare the divisor x+1 to the linear polynomial x−a. If x+1=x−a, what is a equal to? Enter your answer as a number, like this: 42

If x + 1 = x - a then we just need to solve it

x + 1 = x - a

x - x + 1 = - a

1 = -a

a = -1

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
