Answer:
x=-2, y=-3
Step-by-step explanation:
we can rearrange the questions to make it easier
y=3x+3
2y=-3x-12
if you add the two equations, you get
3y=0x-9
so y=-9/3 = -3
plug y into one of the equations
-3=3x+3
-6=3x
x=-2
and then check your work by plugging into the other equation:
2*-3=-3(-2)-12
-6=6-12
-6=-6
It’s like 20 or something
h2 + 52 = 102

Answer: 
<u>Step-by-step explanation:</u>
P(x) = x⁴ - 3x² + 4x + 5
g(x) = x² + 5
<u>_x²_- 8 </u>
x² + 5) x⁴ + 0x³ - 3x² + 4x + 5
-<u>(x⁴ + 0x³ + 5x²) </u> ↓ ↓
-8x² + 4x + 5
-<u>(-8x² + 0x - 40)</u>
4x + 45
