Have you figured it out ?
Answer:
Step-by-step explanation:
Width = w
Length = w + 6
Area = 112 sq. cm
length * width = 112
(w +6 ) *w = 112
w² +6w -112 = 0
Sum = 6
Product = -112
Factors = 14 , -8 {14 - 8 = 6 , (-8)*14 = -112}
w² + 14w - 8w -112 = 0
w(w + 14) - 8(w + 14)=0
(w +14)(w -8) = 0 {Ignore w + 18 as measurement won't be negative}
w - 8 = 0
w = 8 ft
Length = 8 + 6 = 14 ft
Answer:

Step-by-step explanation:
Let x be the width of the jewellery box
Given:
Length of the box is twice its width
Length of the box = 
Length of the box = 
depth of the box is equal to 2 inches less than its width.
depth of the box = 
depth of the box = 
The volume of the box is 64 inches.
Solution:
We know that the formula of the volume is.

Now we substitute all known value in above.



Therefore, the equation of the volume of the box is.
