Step-by-step explanation:
The answer is A. (x - 4)(x - 12).
I'm afraid I don't see the models you have written about although I do know the answer. (C= Courtney's age, S= Shilo's age)
Shilo is 7 years older then Courtney, which equals to C+7=S.
While at the same time Shilo is 13 years younger then twice Courtney's age. This turns into Cx2-13=S.
c+7=cx2-13. This is the equation, now lets work it out.
Add 13 on each side and you get
c+20=2c
Now we subtract c from each side and we get
20=c Therefor we have found out that Courtney is 20 years old.
Shilo being 7 years older then Courtney is 27
We have question

<span> /*8 (multiply both sides by 8)</span>

/*6 (multiply both sides by 6)

/-30 both sides
8W=-66-30
8W=-96
W=-12
