Answer:
The second one
Step-by-step explanation:
......................
L=w+4 this shows the length is 4 inches longer than width
h=w-2 this shows the height is 2 inches shorter than the width
volume=lwh
so 240=lwh=(w+4)(w)(w-2)
simplify and solve to find the width then you can use that to find the other values as well.
X - y = 5 in slope intercept form is y = x - 5
If you mean as a decimal, it's 30.125.
