Answer:
First we need to calculate the are of each wall, since we alredy knew the length (l) and the width (w) which is the height of the wall in this case:
A = wl = 9 . 12 = 108 (ft²)
We also know that he painted 3 walls, we need to multiply our first result by 3, in other words, the area of wall that Brett painted is the sum of the area of three walls: 108 . 3 = 324 (ft²)

Answer:
2.1
Step-by-step explanation:
It's quite simple. Look:
Lets let S- be the age of Sally and B- can be the age of Beth
S+B=60
S-6=3(B-6)
S-6=3B-18
S=3B-18+6
S=3B-12
3B-12+B=60
4B=60+12
4B=72
B=72/4
B=18
B=60-18
B=42
The ages are (B)18 and (S)42
Hope this helps!! :)
