Answer:
2:53
Step-by-step explanation:
I believe that you are subtracting times here, so have in mind that if the first number indicates hours, and the second number minutes, and you are asked to subtract more of one quantity (minutes for example) than what you have, you will need to convert some of the hours into minutes.
Recall that 1 hour equals 60 minutes.
in the difference 4:08 minus 1:15, you sre expected to subtract minutes from minutes and hours from hours. Now the number of minutes you need to subtract from 08 is 15 (larger than 08) so we need to convert 1 hour into minutes in the first expression, and then (with enough minutes to deal with), we can subtract:
4:08 is the same as 3:68 where we converted 1 hour to 60 minutes and added those 60 minutes to the existing 8 .
Now the difference can be performed:
3:68 - 1:15 = (3-1):(68-15) = 2:53

Answer:
Step-by-step explanation:
We have been an integral 
. We are asked to find the general solution for the given indefinite integral.
We can rewrite our given integral as:
Now, we will apply the sum rule of integrals as:
Using common integral 
, we will get:
Now, we will use power rule of integrals as:
We know that integral of a constant is equal to constant times x, so integral of 1 would be x.
Therefore, our required integral would be .
Answer:
88 cm²
Step-by-step explanation:
6*2*2+2*2= 28 cm² sides
6*3*2= 36 cm² top and bottom
3*4*2= 24 cm² front and back
28+36+24= 88 cm²
