Answer:

\boxed{\sf \ C \ is \ the \ correct \ answer \ ! \ }

Step-by-step explanation:

fog(x)=f(g(x))

so it comes

f(g(x))=f(x+1)=4(x+1)^2

<u>so C is the correct answer</u>

Answer:

Option B

Step-by-step explanation:

f(x) = 4x^2\\g(x) = x+1

Multiplying both will give us:

(fg)(x) = 4x^2(x+1)

=> (fg)(x) = 4x^3+4x^2

Answer:

  9 3/4

Step-by-step explanation:

Strategy: first cancel the fraction part of the mixed number, then subtract the remaining fraction from the integer obtained.

10 1/2 - 3/4 = 10 1/2 - 1/2 - 1/4

= 10 -1/4

= 9 3/4

__

Strategy: turn the subtracted fraction into a whole number by adding 1/4 to both parts of the problem, then subtract the whole number.

10 1/2 - 3/4 = (10 1/2 +1/4) -(3/4 +1/4)

= 10 3/4 -1

= 9 3/4

_____

We assume that you know that 1/2 + 1/4 = 3/4, or 3/4 -1/2 = 1/4. If you need to, you can get there by using the equivalent: 1/2 = 2/4.
