Answer: 12

Step-by-step explanation:

You can use what is called geometric mean to solve this.

The hypotenuse of this triangle is split into two sections. One section corresponds to/equal to the altitude which is our "X", which corresponds to/equal to the second section.

You find "X" by using geometric mean and the proportion:

16/X=X/9

Then cross multiply to get 16 x 9= 144

then 144=x²

Solve for X.

X=12

Answer:

C. 4 times x squared plus 6 times x minus 3 minus 12 over the quantity 2 times x plus 1

Step-by-step explanation:

f(x) = 8x^3 + 16x^2 − 15

g(x) = 2x + 1.

f(x) / g(x) = (8x^3 + 16x^2 − 15) / (2x + 1)
