Answer:
19
Step-by-step explanation:
My teacher explained it to me.
Let x , y be the numbers;
We have the equation: x + y = 36 and x = 3y - 4 ;
Then, 3y - 4 + y = 36;
4y - 4 = 36 ;
4y = 40;
y = 40 ÷ 4;
y = 10 ;
x = 36 - 10 ;
x = 26;
Answer:
140 in^3
Step-by-step explanation:
The volume formula can be written as ...

A = (20 in^2)(7 in)
A = 140 in^3
The volume of the box is 140 cubic inches.
