Answer:
3,14 because they are the only numbers that are the same in both sets. just compare it to a matching game, what are the same and what are not? if they are different then that is not apart of your answer.
The surface area of the pentagonal prism is 648 square inches.
Step-by-step explanation:
Step 1:
The surface area of a shape is the sum of all the areas of all the external surfaces.
The pentagonal prism has a total of 7 sides i.e. 2 pentagonal sides and 5 rectangular sides.
The total surface area of the prism is the sum of the individual areas of the 7 sides.
Step 2:
The area of the 2 pentagonal sides
square inches.
The area of each rectangular side is 80 square inches. So
The area of 5 rectangular sides
square inches.
The total surface area of the prism
square inches.
The surface area of the pentagonal prism is 648 square inches.
Answer:
4x + 5y = 15
-4x + y = 7
6y = 22
y = 22/6 = 11/3
-4x + 11/3 = 21/3
-4x = 10/3
x = -40/3
