Answer:
B. (2 + 5).
Step-by-step explanation:
18 + 45 = 63
The prime factors of 63 = 3*3*7
So 63 is a multiple of 7.
The answer is (2 + 5) (=7).
2x + 5x + 4 = 25
7x + 4 = 25
7x = 25 - 4
7x = 21
x = 21/7
x = 3 <==
I believe the answer is C but don’t take my word on it
Answer: C looks like the best fit.
Displacement x would be in terms of length, while t would be in terms of time.
Therefore the equation would have units of:
length = (b)*time^2
b = length/(time^2)
Therefore, the units of the constant b should be in length per time^2 (for example, in m/s^2, such as in acceleration).
