Step-by-step explanation:
x + y = 72
x - y = 40
x = y + 40
so, the first equation is then
y + 40 + y = 72
2y + 40 = 72
2y = 32
y = 16
x = y + 40 = 16 + 40 = 56
To solve for x, the first thing to do is to distribute the 4 to (x-2). When you do this, you should get 4x-8=4x+10
Then, subtract 4x from both sides and then you are left with -8=10. Because -8 is not equal to 10, meaning the equation you are left with is not a true statement, the answer to this would be that there are no real solutions.

Answer:
204 in^3
Step-by-step explanation:
The volume of the base square is V=lwh.
When we substitute our givens, it becomes V=6(4)(2). This equals 48 in^3.
The volume of the triangle is V=.5lwh.
When we substitute our givens, it becomes V=.5(6)(4)(15-2). This equals 156 in^3.
When we add 48 and 156, we get 204 in^3.
Hope this helps :)
