Answer:
Step-by-step explanation:
Width =w
Length = w + 6
Perimeter of rectangular room = 54 m
2*(length +width ) = 54
2*(w +6 + w) = 54
2*(<u>w +w</u> + 6) = 54 {Combine like terms}
2*(2w + 6) = 54
Use distributive property
2*2w + 2*6 = 54
4w + 12 = 54
Subtract 12 form both side
4w = 54 - 12
4w = 42
Divide both sides by 4
w = 42/4
w = 10.5 m
Length = 10.5 + 6 = 16.5 m
Length = 16.5 m
Width = 10.5 m
Answer:
A) y=0.04
Step-by-step explanation:
Answer:
Length= 81 feet
width = 73 feet
Step-by-step explanation:
P=2{(8+W)+W}
308=2(8+2W)
308=16+4W
308-16=4W
292=4W
W=73
And length = 8+W
8+73=81
Because scientific notation has to be in between 1 and 10, you would need this to be 5.2. Count the spaces and since its getting smaller your exponent is negative.
Your answer should be 5.2*10^(-3)
