Answer:


Step-by-step explanation:
We have been given that the Rumpart family is building a new room onto their house. The width of the new room will be 16 feet. 
The length of the room will be 4% greater than the width. This means that length of new room will be 16 feet plus 4% of 16.




Therefore, the expression  represents the length of new room and the length of new room is 16.64 feet.
 represents the length of new room and the length of new room is 16.64 feet.
Since we know that area of a rectangular shape is width times length.



Therefore, the area of the new room will be 266.24 square feet.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
<em>Cost of game = $120</em>
<em>Current savings = $30</em>
<em>Rate for babysitting (per hour) = $5/hour</em>
<em></em>
<em>So, required equation is :-</em>
<em>120 = 5h + 30</em>
<em>5h = 90</em>
<em>h = 18</em>
<em></em>
<em>She must make $90 by babysitting for 18 more hours.</em>

Answer:
D
Step-by-step explanation:
Height: h
Length: 2h + 15
Area = length × width 
4h² + 42h + 90
2(2h² + 21h + 45)
2[2h² + 15h + 6h + 45]
2[h(2h + 15) + 3(2h + 15)]
2(h + 3)(2h + 15)
Width = 2(h+3) = 2h + 6
Length: 2h + 15
Difference:
(2h + 15) - (2h + 6)
2h + 15 - 2h - 6
9
Width is 9 feet shorter than the length
