Which of the following is a solution to the equation 4x2+4x−3=0? -1.5

-0.5

1

3

-1.5

Step-by-step explanation:

4x² + 4x - 3 = 0

(2x + 3)(2x - 1) = 0

2x + 3 = 0  or  2x - 1 = 0

x = -3/2   or x = 1/2

-1.5

if you mean 4 times 2 + 4x - 3 = 0 then the answer is:

x = -5/4 (-1.25)

If you mean 4x2 + 4x - 3 = 0 then:

x = 0.5 or -1.5

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
