Which expression is equivalent to 4n(6n + 2m)? A 24n + 4n + 2m
B (4n + 2m) x 6n
C 24n2 + 8mn
D 10n2 + 6mn

c maybe

Step-by-step explanation:

4n(6n+2m)

24n²+8mn

C, 24n²+8mn

Step-by-step explanation:

So because 4n is on the outside of the bracket, you have to times everything on the inside of the bracket by 4n.

So, you do:

4n×6n=24n² (4×6=24 and n×n=n²)

4n×2m=8mn (4×2=8 and n×m=mn)

Then you add 24n² to 8mn like this:

24n²+8mn

Hope this helps :)

sorry not sure

step-by-step explanation:

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
