Which is the simplified form of the expression m + 3m + 2 + 2?

If you want to factor it, it will be 4(m+1).If not factored, it will be 4m+4

Step-by-step explanation:

m+3m+2+2

m+3m = 4m

2+2 = 4

4m+4

To factor that, you can take out 4 as a common factor, so it will be (4)(m+1)

4m+4

Step-by-step explanation

answer: 819.89 miles across america

step-by-step explanation:

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
