42=(2w-6)+(2w-6)+w+w
42=6w-12
54=6w
w=9
42=2l+18
24=2l
l=12
length= 12cm, width= 9cm
Jayla= x
keisha= x+ 3
melanie= x + 6
to solve:
42= x + x + 3 + x + 6
42= 3x + 9
-9 -9
33=3x
———-
3
x=11
therefore
jayla is 11
keisha is 14
melanie is 17
The slope is 3 and the point is (0,-13)
17.5% is greater than 1/6
