First you rewrite all the expressions like this:
8x+4=(2x+12)+(2x+4)
then you solve and get:
x=3
to solve for AC, you have to solve 8x+4 by replacing x with 3
8x+4 would be rewritten as:
8(3)+4
AC=28
Answer:
perimeter = 6w + 5 units
Explanation:
Perimeter of a rectangle can be calculated as follows:
Perimeter = 2(width + length)
We are given that:
width = w units
length is 5/2 units greater than twice the width. This means that:
length = 2w + 5/2
Now, substitute in the above equation to get the expression for the perimeter as follows:
Perimeter = 2(width + length)
Perimeter = 2(w + 2w + 5/2)
Perimeter = 2(3w + 5/2)
Perimeter = 2(3w) + 2(5/2)
Perimeter = 6w + 5
Hope this helps :)
