Answer:
D. 25°
Step-by-step explanation:
Plug in the -1 inside the given equation:
y=2x²-5x+9-78-38-18-1
y=2(-1)²-5(-1)-126= -119
Answer:
x = 40
Step-by-step explanation:
2x = 4x - 40 (recall properties of a parallelogram)
Solve for x
2x - 4x = 4x - 40 - 4x (subtraction property of equality)
-2x = -40
-2x/-2 = -40/-2 (division property of equality)
x = 20
I think the answers are A and C. Hope this helps ☺
