Question

PLEASE HELP!!!!!

The perimeter of the fighter below is 30 feet. Write an equation and solve for x.

Answer 1

Equation:
`30=2(x-2)+2(2x+3)`

`x:(14)/(3)`

Explanation:

By definition, the perimeter of a figure can be calculated by adding the lenghts of its sides.

Knowing this, you can write the following equation:

`P=2(x-2)+2(2x+3)` [Equation 1]

According to the data given in the exercise, the perimeter in feet of the fighter is:

`P=30`

Therefore, you can substitute this values into [Equation 1]:

`30=2(x-2)+2(2x+3)`

Finally, you must solve for "x" in order to find its value. This is:

`30=6x+2\\\\30-2=6x\\\\(28)/(6)=x\\\\x=(14)/(3)`
