1 answer:

5 0

You can multipy the entire thing by 21 to solve for x

$\frac{2}{3}x -3= \frac{2}{7}$
$21( \frac{2}{3}x -3= \frac{2}{7} )$
$14x -63= 6 
$
$14x= 4+63$
$14x= 67$
$x= \frac{67}{14}$

The volume of a packing box is 5 – x cubic feet. The width of the box is x feet and the length is x – 2 feet. The height is give

photoshop1234 [79]

By definition we have that the volume is given by
V = h * w * l
where
V: Volume
h: height
w: width
l: length
Clearing the height we have:
h = V / (w * l)
h = (5 - x) / ((x) * (x - 2))
The expression is not defined for the values of x that make the denominator zero:
((x) * (x - 2)) = 0
x = 0
x = 2
Answer
h = (5 - x) / ((x) * (x - 2))
x = 0
x = 2
