The length of a rectangle is four times its width. if the perimeter of the rectangle is 90 cm, find its length and width

length 36, width, 9.

Step-by-step explanation:

you are trying to find "X" and it's 4 times the size of y, the whole thing is equal to 90. it would look like this

y=4x

y(4x) + x = 90

5x=90

90/5= 18

the rest is the "y" value, 72.

divide both by 2 because rectangles have 4 sides, and you get the answer above.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
