Answer:
B
Step-by-step explanation:
You are combining like terms.
1.) find all of the #x³ and there is only one and that is -x³ so that limits the problem to B or D.
2.) now you find all of the #x² and there are three of them being 10x², -x², and 4x². Now that you have identified them you will add them together to get a sum of 13x²
you don't have to do anymore of the question because D does not have 13x² so it is B.
I honestly don’t know the answer to this question but I hope you find an answer soon and good luck

Answer:
135.7 milliseconds
Step-by-step explanation:
The relationship between force, mass, and acceleration is ...
F = Ma . . . . . we use M for mass, so as not to confuse with m for meters
The relationship between acceleration, velocity, and time is ...
v = at
The fraction of the applied force that is in the horizontal direction is ...
2000N·cos(20°)
Solving for a and t, we get ...
a = F/M
t = v/a = v/(F/M) = Mv/F
t = (85 kg)(3 m/s)/(2000cos(20°) kg·m/s²) ≈ 0.1357 s
The sprinter took about 135.7 ms to push off.
