The lengths of the sides of a triangle are y, y+1, and 7 cm if the perimeter is 56 cm what is the value of Y?

Respuesta :

So first you combine all the equations and make them add up to 56.


The equation should look as such: 2y + 8 = 56


Then we solve for y


Work: 2y + 8 = 56

2y = 48

y = 24


I hope this helps!

y + y + 1 + 7 = 56

2y + 8 = 56

2y = 48

y= 24 (answer).
