2x^2 - 7x + 5 - (-6x^2 - 4x - 2) =
2x^2 - 7x + 5 + 6x^2 + 4x + 2 =
8x^2 - 3x + 7 <==
Using the distance formula:
Distance = √((x2-x1)^2 + (y2-y1)^2)
Distance = √((5-2)^2 + (-8 - -4)^2
Distance = √(3^2 + -4^2)
Distance = √(9 +16)
Distance = √25
Distance = 5

the the negative angle is -(2π-π/4)= -\frac{7 \pi }{4}
Answer: 20
Step-by-step explanation:
40/2 = 20
140/7 = 20
also if you look at the middle of 0 and 2 and go up to where the line is, its between 40 and 0 so its 20.
