The dimensions in inches of a shipping box can be expressed as width x, length x + 1, and height x - 4. the volume is 84 ft^3. find the dimensions of the box in feet.

1, 1, 4
2, 2, 21
2, 6, 7
3, 4, 7

? if somebody can put this into an equation for me, i can do the rest.

The dimensions of the box are

Step-by-step explanation:

we know that

The volume of a box in the shape of a cube is equal to

where

W is the width of the box

L is the length of the box

H is the height of the box

In this problem we have

Substitute the values in the formula of volume

Using a graphing tool

Solve the cubic function

see the attached figure

The value of x is equal to

the dimensions of the box are

c

step-by-step explanation:

at least i think its

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
