The area of a rectangular prism is the area of 6 surfaces. That is, 3 pairs of surfaces. Each of the three pairs will have one of the sets of dimensions ...
- length × width
- length × height
- width × height
In order for a net to be a net useful for calculating the prism surface area, it must have 3 pairs of rectangles with these dimensions. The description above matches that requirement.
___
Please note that no two surfaces with the same pair of dimensions are adjacent.
Answer:2
Step-by-step explanation: Add the two to the other side to leave your variable as the only term on the left then divide out the 9. 18/9 equals 2, giving you your answer.
its (a) because (a) is C(x)=3x4+30x and 9+21 is 30 so its 3x2+30
