1. What is the value of y? What is the perimeter of ? Show your work.

Answer:
y = 3
Perimeter: 17 ft
Step-by-step explanation:
3y - 2 = y + 4
2y = 6
y = 3
Perimeter: 4 + 6 + (3 + 4)
10 + 7
17
Both triangles are the same dimensions set the two equations equal and solve for y:
3y -2 = y +4
Add 2 to both sides:
3y = y + 6
Subtract 1y from both sides:
2y = 6
Divide both sides by 2:
Y = 3
Perimeter = ((3(3)-2 =9-2= 7):
7 + 4 + 6 = 17 feet
