Answer: 5 hours
Step-by-step explanation: 5 hours because 7/5 *5/1=35/5 and 35 divided by 5 equals 7

now you must first distribute the 2 in the brackets. multiply 2 by h and (-29)

now combine "like terms" (-58) with (-58) and 2h with (-h)

now that h has no coefficient (no number in front) you can bring the -116 over to the other side to isolate the variable (h). remember when you bring a number over the equal sign the signs change so (-116) becomes 166.

now add the two terms together

the final result is 157
1st you're going to want to divide the figures into smaller parts. I deviated them and got the measurements 2W, 1L, and 2H. The formula for rectangular prisms is LxWxH and I got 4.
Now we need to use the same formula for the other figure.
4L, 2W, and 1H.
Multiple them all and we get 8
Now we take the Volume of both the figures and add them together 8+4 = 12
So, the volume of the composite figure is 12
