Answer:
Explanation:
So its a rectangle which means it has 4 sides
two of the sides are x feet long
and two of them are 2x -3 feet long
we also know that all of the sides together are 48 feet long
so the equation would look like
2(x)+2(2x-3)=48
or x+x+2x-3+2x-3=48
It doesn't matter which one you use because they both simplify to
6x-6=48
add 6 to both sides
6x=54
divide both sides by 4
x=9
