Add the same ones together
(4n^3 + 3n^3) + (-4n + 7n) + 8
your answer:
(7n^3) + (3n) + 8 or 7n^3 + 3n + 8 (you don't exactly need the paranthesis)
hope this helps
Take the complex zero 1+i. There must be another zero 1-i to balance it, so we have the factors (x-1-i)(x-1+i)=x²-2x+1+1=x²-2x+2.
So the polynomial is (x+3)(x²-2x+2)=x³-2x²+2x+3x²-6x+6=x³+x²-4x+6, option D.
The distance is increasing at a rate that is the speed of the plane multiplied by the cosine of the angle between its flight path and the direct line to the radar station. That cosine is 4/√(3²+4²) = 4/5, so the distance is increasing at
440 mi/h × 4/5 = 352 mi/h
Answer:
20 minutes
Step-by-step explanation:
It would take 20 minutes longer for Linda to type 8 pages that contain 500 words on each page.
Step-by-step explanation:
x^2+2x+7y=15
7y=15-x^2-2x
y=15/7-1/7x^2-2/7x , x ∈ all real numbers
