Square:
We know all sides of a squares are equal in length.
s= the length of one side of the square.
45= s+s+s
45= 3s
s=15 inches
Each side of the square is 15 inches.
Rectangle:
length(l)= ????
Width(w)= s = 15 inches
l -w= 5inches
l- (15 inches)= 5 inches
l = 20 inches
Answer:
A length of the rectangle is 20 inches long.
First, multiply the 2 times (x-5) and you get 2x-10 on the left side.
Then on the right side, add up all the similar terms and you get 30 (the -3x and +3x cancel each other out.
2x-10=30
Then add 10 to both sides and you get 2x=40.
Then divide both sides by 2 and you get x=20.
Answer is B.
So 9% of 13 is 1.17
so then you go $13 - $1.17 and your answer is $11.83
