In this question, they gave you the system of equations. You just need to use the two of them.
We want to find the m or the number of the multiple-choice questions. So we need to turn our last equation in the form of 'm's by translating the 'f's into 'm's.


If we know the m form of f, we can convert the second equation and find the answer:

Plug in the m value of f:

Distribute the 5:

Subtract -75 from both sides:

Combine like terms:

Divide both sides by -2:

So, we learned that the number of the multiple-choice questions is 12.
Answer:
C
Step-by-step explanation:
The answer is: " (x − 8) (x + 3) " .
__________________________________________________________
" (x − 8) (x + 3) " are the factors of: " x² − 5x − 24 " .

Explanation:
__________________________________________________________
Given: "x² − 5x − 24 " ; Factor this "trinomial" expression completely.
We notice the "-5x" and the "-24 .
What factors of "-24" add up to "-5" ?
-1 + 24 ? No.
-24 + 1 ? no.
-12 + 2 = -10? No.
12 + (-2) = 12 - 2 = 10 ? No.
-3 + 8 = 5 ? No.
-8 + 3 = -5 ? Yes!
So: " (x − 8) (x + 3) " are the factors of: " x² − 5x <span>− 24 " .
