Second one tell me if im wrong
P = 2L + 2W
L = 7
W = 5
P= ???
P = 2*7 + 2*5
P = 14 + 10
P = 24 feet of lace.
5r-4 and r=-5 so it would be 5(-5)=-20, then -4 , so is is -24
<u>Answer:</u>

2×8=16
7×3=21
2/3 + 7/8 = 16/24 + 21/24
Answer:
x=21/23
Step-by-step explanation:
Solve for x:
3x+5y=21−20x+5y
Add 20x to both sides:
3x+5y+20x=−20x+5y+21+20x
23x+5y=5y+21
Subtract 5y to both sides:
23x+5y+−5y=5y+21+−5y
23x=21
Divide both sides by 23:
x=21/23
