Length = 2x - 5
Width = x
Perimeter = 146
P = 2L + 2W
146 = 2(2x - 5) + 2x
146 = 4x - 10 + 2x
146 = 6x - 10
146 + 10 = 6x
156 = 6x
156/6 = x
26 = x
Length = 2(26) - 5
Length = 52 - 5
Length = 47 cm
Width = 26 cm

Answer:
44
Step-by-step explanation:
f(x) = x + 2.....change f(x) to y
y = x + 2....now switch x and y and solve for y
x = y + 2
x - 2 = y....change y to f-1(x)...represents an inverse
f-1(x) = x - 2 <== ur inverse
1. a^-b
2.a^b/a^c
3.a^c/b^c
b
c=42
s=30
