Answer:
Slope for #17 is 3/2
Slope for #18 is -18
Step-by-step explanation:
Rectangle:
P = 2 (L+W) but length is 2 meters longer than wide
then L = W + 2, So
P = 2 (L + W)
24 = 2(W+2+W)
24 = 2 (2 + 2W)
24 = 4 + 4W
So 4W = 24 -4 =20
W = 20/4= 5, L = 5+2= 7
Double check
24 = 2*(5+7) = 2 *12 = 24
2x+3=3
I you're looking for x...
2x+3=3
-3 -3
2x=0
/2 /2
x=0
