Answer:
A
Step-by-step explanation:
15^2 = 225 (memorize everything to 20, thank me later)
39^2 = 1521 (just use a calculator for everything higher)
225 + 1521
1521 =?= 45^2
45^2 = 2025
1521 =/= 2025
Just to be sure, I'll do 15^2 + 45^2 (going to be too much)
225 + 2025 = 2250
2250 =/= 1521
x = -2
y = 1
-3x - 4y = 2
3x + 3y = -3
