Im not sure if you wrote this wrong because (x+y)2 does equal x2+y2. An example would be if x equals 3 and y equals 4 (3+4)2=(3)2+(4)2 (7)2=6+8 14=14.

Answer:
y = -4x - 12
Step-by-step explanation:
y + 4 = -4(x + 2)
y = -4x -8 - 4
y = -4x - 12
slope=0
it's a straight horizontal line when you graph it.
2 x 15 = 30, 9 x 22 = 198, 198 + 30 = 228.
So the answer is A 2 children, 9 adults.
