Question

The perimeter of an equilateral triangle is 63 inches. If the length of each side is (4x-3) find the value of x

Answer 1

X=6

Explanation:

We know that the perimeter is the sum of all its sides.

`P=63\\P=(4x-3)+(4x-3)+(4x-3)\\P=P\\(4x-3)+(4x-3)+(4x-3)=63\\12x-9=63\\12x=72\\x=(72)/(12) \\x=6`
