To do this we take the outlier off the parenthesis (the 4) and multiply it by the two numbers inside the parenthesis...
4*7 + 4*8
28+32
600kb in 24 seconds to find out how many kbs per second divide by 24
600/24 is 25kb
The answer to one would be 25534
Answer: 
Step-by-step explanation:

Answer:
The force exerted by the weight lifter is 81.7 N.
Step-by-step explanation:
We can find the force exerted by the weight lifter using the definition of work:
(1)
Where:
F: is the force
d: is the displacement
We have W = 9.8 J of work and d = 0.12 m, so by solving equation (1) for F we have:

Therefore, the force exerted by the weight lifter is 81.7 N.
