Answer:
7a
Step-by-step explanation:
You would just add the two numbers and put the a in front of the answer. It would be 2 + 5 (which is 7) then put the a after the 7.
2n(n + 3) - 5(n + 3) = (2n-5)(n+3)
A. (n + 3) (2n - 5)
The answer would be B) 6x + 2.
5x + 2 + x (simplify)
(5x + x) + 2 (gather like terms)
6x + 2 (simplify).
Answer:
(-239.4, 657.8) km/h
Step-by-step explanation:
Measured CCW from the +x axis, the angle at which the airplane is traveling is 110°. Then the (x, y) components of the velocity vector are ...
(700 km/h)(cos(110°), sin(110°)) ≈ (-239.4, 657.8) km/h
