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

Answer:

X=6

Step-by-step explanation:

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

$P=63\\P=(4x-3)+(4x-3)+(4x-3)\\P=P\\(4x-3)+(4x-3)+(4x-3)=63\\12x-9=63\\12x=72\\x=\frac{72}{12} \\x=6$
