Answer:
<h2>length = 22 inches</h2><h2>width = 8 inches</h2>
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 60 in
The statement
the length of a rectangle is 6 inches more than twice it's width is written as
l = 6 + 2w
Substitute the statement into the above formula
That's
60 = 2( 6 + 2w) + 2w
60 = 12 + 4w + 2w
6w = 60 - 12
6w = 48
Divide both sides by 6
w = 8
Substitute w = 6 into l = 6 + 2w
That's
l = 6 + 2(8)
l = 6 + 16
l = 22
The dimensions are
length = 22 inches
width = 8 inches
Hope this helps you
yes i agree with her because elimination method is more simpler and shortest method to solve system of equations.
elimination method use to multiply of both equation in order to balance the variable x or y and then equate them.
example
x+2y=7 .....equation 1
x-3y=14 .......equation 2
so you can multiply equation 1 by -1 in order to equate x and get the value of y by saying equation 1 minus equation 2.
