Respuesta :

the answer is 3 times q + 7 = 40 because there are 4 sides and 3 of the sides are equal as one of them is 7 so you add 7 to the total amount after multiplying q three times
Q = 11. 3q + 7 = 40. Since the q sides are the same length and the total perimeter is 40, you use the equation and get 11.
