A triangular pathway in a park is shown below. what is the approximate total length of the path?

Solve the equation. y + 13 = 10 Y = 23 Y = - 23 Y = 3 Y = - 3 Solve the equation. 9 = t + 13 T = - 4 T = 4 T = 22 T = - 22 Multiply. 7 (x - 2) 7x - 14 7x - 2 X - 14 7x - 9 Solve the equation. X + 1 = 3 X = - 2 X = 4 X = 2 X = - 4
