The height of a triangle is 2 less than 5 times its base. if the base of the triangle is x feet, and the area of the triangle is 12 square feet, which equation models this situation? a. 25x^2-10x-24=0 b. 5x^2-2x-24=0 c. 5x^2-2x-6=0 d. 5x^2-2x-12=0

A. 5x^2 − 2x − 24 = 0

Step-by-step explanation:

height = 5b-2

b =x

We can rewrite the height as

h = 5x-2

We know the formula for area of a triangle

A = 1/2 bh

A =1/2 x * (5x-2)

Distributing the x

A=    1/2 (5x^2 - 2x)

We know A =12

12 = 1/2 (5x^2 - 2x)

Multiply each side by 2

12*2 = 2*1/2 (5x^2 - 2x)

24 = 5x^2 - 2x

Subtract 24 from each side

24-24 = 5x^2 - 2x-24

0 = 5x^2 - 2x-24

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.
