Hello.
Remember the Property of exponents:

Let's use it to solve our maths problem.

Subtract the exponents:

Therefore, the answer is
c.
I hope it helps.
Have a nice day.

First, we'll need the area of a single triangle
then we'll multiply that by 3 to get our answer
to find the are of a triangle, we multiply height times base then divide that by 2
so.. 5 x 10 = 50; 50/2 = 25
if 25 = one triangle
then 25 x 3 = 75 = three triangles
answer - 75 sq. in.

Just replace 'x' in c(x) by d(x)
(cod) (x) = 4(x^2+5x) - 2 = 4x^2 +20x - 2
Thats it!
