Answer: D) Length: 60, Width: 30
Step-by-step explanation:
The totals of the length plus two widths of the other dimensions given do not add up to 120 feet.
I think it is -2288 something like that
1cc means one cubic centimeter. I advise you to look at the letter units
One possible system is
1x + 3y = 4
2x + 6y = 8
Note how 2 is twice as large as 1, 6 is twice as large as 3, and 8 is twice as large as 4.
In other words, the second equation is the result of multiplying both sides of the first equation by 2.
1x+3y = 4
2*(1x+3y) = 2*4
2x+6y = 8
Effectively the two equations in bold are the same which produces the same line. The two lines overlap perfectly to intersect infinitely many times. An intersection is a solution.
