Answer:
. Simplify: (4x2 - 2x) - (-5x2 - 8x).
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2) Step-by-step explanation:
Answer:80 degree angle
Step-by-step explanation:
There are always 180 degrees so you subtract the 2 others and you get the angle (60+40-180)
The answer is quadratic, I took the test.
true
time = distance/speed
3080/770 = 4
So it took 4 hours.
