The base of a triangle is 12 inches greater than the height. If the area is 80 square inches, find the length of the base PLEASE HELP

20 inches

Step-by-step explanation:

We know the triangles base is 12 inches greater than the height and the area is 80 square inches. The formula for finding the area of a triangle is A= b multiplied by h divided by 1/2.

How I found the

80 x 2 = 160 (this is the area before dividing by 1/2)

If 8 were the height, 20 would be the base. (12 + 8 = 20)

20 x 8 = 160 (base x height)

160 divided by 1/2 = 80 square inches

5x-3 or x-3

Step-by-step explanation:

I don't know what are the choices, so I'll just factor the whole thing. Choose the ones that fit.

-3 + -15 = -18

-3 * -15 = 9*5

5x^2-15x-3x+9

5x(x-3)-3(x-3)

(5x-3)(x-3)
