Answer:
B
Step-by-step explanation:
yes, we need two numbers that multiplied with each other results in -48.
that means already that one of them has to be positive and the other negative.
that gives us (with all +/- alternating sign combinations)
2 and 24
3 and 16
4 and 12
6 and 8
to pick from there we see that the "middle" term is -2x.
that means that the absolute value of the negative number has to be 2 more than the positive number (so that when adding the intermediate multiplication terms we end up with -2x).
the only choice is therefore 6 and -8.
and that makes B the right answer.

Answer:
Step-by-step explanation:
237 + 462 ~ 200 + 500 = 700
462 is rounded to hundred. ten's place 6 is there which is ≥ 5. If it is ≥ 5then add 1 to hundred's place.
462 ` 500
Here’s the answer hope it helped :)
so two fellows did all the carpeting in 10 days.
now, how long did "1" fellow work only? well, it worked for 10 days.
how long did the other fellow work for? well, it was working alongside the first one, and it was there for also 10 days.
so the two guys working together, really did 10+10 = 20 "days worth of work". So that the whole carpeting job can be done in 20 "days worth of work".
now if we want to finish it in 4 days, 20 ÷ 4 = 5.
so if we hire 5 guys, since each one will do 4 days worth, 5*4 = 20 <- the whole job.
