35+5(4-s)=2550
35+20-5s=2550
55-5s=2550
-55 -55
-5s = 2495
s = - 499
-499 + a = 4
+499 +499
a = 503

Answer: B (y>2) I hope this helps you
Answer: No
Step-by-step explanation: If you mean 3^-2 it would be 0.111111111 repeating. 3^2 is 9 not -2
Let width be x,
Length: 3+x
P=2(l+w)
54=2(x+(x+3))
54/2=2x+3
27=2x+3
27-3=2x
24=2x
24/2=x
12=x
Therefore, the width is 12 inches and the length is (12+3)=15 inches
Hope I helped :)
