Question

The triangle and the square shown have the same perimeter. solve the equation 3x 4x 5x=4(x 2) to find the value of x . then find the length of one side of the square.

Answer 1

x = 1

Explanation:

3x 4x 5x=4(x 2)

Mathematical operators seem to be missing. Is this supposed to be:

3x + 4x + 5x=4(x+2) ?

Assuming it is:

3x + 4x + 5x=4(x + 2)

12x = 4x + 8

8x = 8

x = 1
