What is the quotient of x2 +7x +12 and x + 4?

q = x + 3

Step-by-step explanation:

q = (x^2 + 7x + 12)          factor the numerator

         x + 4

q = (x + 3)(x + 4)

          (x + 4)

Notice that the x + 4's cancel

q = (x + 3)

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
