Answer:
it's actually 28+/-√721/7
Step-by-step explanation:
We are given a six-sided cube. To determine the surface area and the volume of the cube, we need to know the area of one side:
All sides of the cube are squares with side, s. The area of one square is
A = s^2
The surface area of a cube is the sum of all areas of the sides. So
SA = 6 sides * s^2
SA = 6s^2
The volume of the cube is
V = s^3
The volume of the cube represents the total solid area of the cube which includes the space inside the solid.
You need a picture of the shape.
(5, 3)
x y
Plug in:
x + y = 8
5 + 3 = 8
8 = 8
Plug in:
17(5) + 17(3) = 8
85 + 51 = 8
136 = 8
Answer - No, (5, 3) is not a solution to this system of equations.
