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:
Step-by-step explanation:
x^2 - 17 x + 60
we should find two numbers such that their sum is equal to -17 and product is equal to 60
The two numbers are -12 and -5
now, x^2 - 12 x - 5 x + 60 { splitting the middle term }
x ( x- 12 ) - 5 ( x - 12 )
= ( x - 5 ) ( x - 12 )
hope this helps

Answer:
The correct answer is 12 and a half or 13 weeks.
Step-by-step explanation:
First, convert the values to decimals.
27 1/2 = 27.5
2 1/4 = 2.25
Then, divide miles of road that need to be repaved by the number of miles that are repaved per week.
27.5/2.25 = 12.2222222222222
Round that up to 12 and a half weeks or 13 weeks.
