Question

The perimeter of an equilateral triangle is 63 inches. If the length of each side is (4x-3), find the value of x. Equilateral means all sides are equal.

Answer 1

Explanation:

3*(4x - 3) = 63 Divide both sides by 3

4x - 3 = 63/3

4x - 3 = 21 Add 3 to both sides

4x = 21 + 3

4x = 24 Divide by 4 on both sides

4x/4 = 24/4

x = 6

Note: The perimeter is the sum of all three sides. One side is 4x - 3 All 3 sides must be 3*(4x - 3)
