Answer:
8 inches
Step-by-step explanation:
You first divide 240 by 3 which is 80
Then you find what number is 2 less than the other number that is you multiplied together you get 80
And we know that 8 × 10 = 80
There for the :-
Width is 8 in
Length is 10 in
Hight is 3 in
The proof is if you multiply all of them you have to get 240
And if you multiply 8, 10, and 3 you get 240

Answer:
x=(-13/5), y=(-6/5)
Step-by-step explanation:
I will do step by step since I dont see a picture.
when you add them it gets rid of the y,
5x=-13
divide out the 5
x=(-13/5)
plug this into the first equation
2(-13/5)-y=-4
-5.2-y=-4
add 5.2 to each side
-y=1.2
divide out the negative
y=-1.2 or (-6/5)
