James solved 4 problems/6 min

That is 1.5 problems/min

Since there is 60 minutes in an hour, you multiply 1.5 by 60 and you get 90 problems in an hour.

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
