Step-by-step explanation:
In this equation there are few key numbers, thankfully XD, so it does not take too long to figure out that the 0.04 is clearly a tax on the repairs as 30h is representing the hours spent repairing Kimber's phone.
A = length x width
15,000 = (w + 30) x w
15,000 =

+ 30w
0 =

+ 30w - 15,000
Use quadratic formula to find that w= -15 + or - 5

. Because distance cannot be negative, the width is -15 + 5

meters or approximately 108.39 meters. This means that the length is approximately 138.39 meters.
Answer:
Option B. The volume is the product of the area of the base, 2x(2x + 5), and the height, 2x – 3
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
The volume of a rectangular prism is equal to

where
B is the area of the base of the prism
H is the height of the prism
In this problem we have
The area of the base B is equal to

The height H is equal to

therefore
The volume is equal to

The volume is the product of the area of the base, 2x(2x + 5), and the height, 2x – 3
11.04 = 10(1.02)^n
1.104 = 1.02^n
ln 1.104 = ln 1.02^n
ln 1.104 = n ln 1.02
n = ln 1.104/ ln 1.02
n = 4.99630409516 (5 if rounded)
