Answer:
(6, -8)
Step-by-step explanation:
Solve this system by substitution: substitute (1/3)x - 10 for y in the second equation, obtaining:
2x + (1/3)x - 10 = 4, or (after multiplying both sides by 3):
6x + x = 42, or 7x = 42.
Then x = 6. Substituting this into the first equation, we get:
y = (1/3)(6) - 10 = -8
The solution is (6, -8)
20+20+24+24=88
88/2=44
88+44=132
If you split it so there is a rectangle and a triangle, you find the perimeter of the rectangle then divide it in half.
