Answer:
Step-by-step explanation:
it should add up to 360°
360=135 + 120 + 7x-64+5x-4+3x+31+4x+15+6x-8 (seems like too much huh)
360=225+25x ( much better just add the x terms and the constants together)
135 = 25x ( just subtract 225 from each side of the equation)
5.4 = x ( divide 135 by 25 )

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

Answer:
-2
Step-by-step explanation:
