Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask
Write an equation based on the problem in the terms of x and solve the equation
first number + second number + third number = 240
x + x + 1 + x + 2 = 240
3x + 3 = 240
3x = 240 - 3
3x = 237
x = 237/3
x = 79
The smallest number, x, is equal to 79
Find the next two numbers
the second number = x + 1
the second number = 79 + 1
the second number = 80
the third number = x + 2
the third number = 79 + 2
the third number = 81
ANSWER: The three numbers are 79, 80, 81
Answer:
This would be the same as an isosceles right triangle. It would be 61ft x (square root of 2) = ~86.3ft
This is rounded of course...

Answer:
I think it should be
Step-by-step explanation:
When the question said area of the cube, I think it was supposed to be surface area, which would where a is the length of one edge. Given that the length of one edge is 2x, we would plug in 2x to the equation to get which would become .
