Answer: Calculate the volume of each individual figure and add them.
Step-by-step explanation:
1. A composite figure is formed by two or more figures.
2. Then, to calculate the volume of the composite figure you must calculate the volume of each individual figure and then you must add all the volumes obtained.
3. For example, if a composite figure has a cylinder and a cone, the volume of the composite figure will be the sum of the volume of cylinder and the volume of the cone:

Answer:
maybe 3...............................
1. 4(n+3)=16, n+3=4, n=1
2. m/4+3=24, m/4=21, m=84
1. three added to a number n implies n+3, 4 times that sum is 4 (n+3), to solve divide both sides by 4 then subtract three from both sides.
2. a number divided by 4 means n/4 adding it to three n/4+3, to solve subtract 3 from both sides then multiply both sides by 4
