7
Step-by-step explanation:
3x-2x-4=2x-2x+3
x-4=3
x-4+4=3+4
x=7
Answer:
B
(x-2) is a factor since remainder is 0.
Step-by-step explanation:
We divide (x-2) into the polynomial
through long division or synthetic. We choose long division and look for what will multiply with (x-2) to make the polynomial
.
![(x-2)(-4x^3)=-4x^4+8x^3](https://tex.z-dn.net/?f=%28x-2%29%28-4x%5E3%29%3D-4x%5E4%2B8x%5E3)
We subtract this from the original
.
This leaves
. We repeat the step above.

Answer:
Step-by-step explanation:
Draw a picture. You have an isosceles right triangle. Each leg is 50 ft.
tanθ = 50/50 = 1
θ = arctan(1) = 45°
