15 x 25 = 375
15 x 50 = 750
375 + 750 = 1,125
She has 1,125 books.
13.) A=9cm^2
If the area is l•h, and there are 9 cubic squares, that means that the length of each side on the square is 3cm, each square on it equals 1cm.
14.) V=27cm^3
If the volume is l•w•h, then we find the third power square root of 27, so 3•3=9•3=27, the answer is 3cm for the length, width, and height.
15.) V=4,913cm^3
If volume is l•w•h, then what number when raised to the third power equals 4913? The answer is 17, since 17•17=289•17=4913. So the length is 17cm
16.)V=216cm^3
If volume is l•w•h, then what number when raised to the third power equals 216? The answer is 6, since 6•6=36•6=216.
17.)A=121
Is area is l•w, then what number raised to the second power equals 121? The answer is 11, since 11•11=121. Therefore it WILL NOT fit a car with a length of 13ft.
18.)A=141
If area is l•w, then what number raised to the second power equals 141? The answer is 12, since 11.87•11.87=141 (answer was rounded to nearest whole number) meaning that she will need 12ft of fence to enclose her garden.

Answer:
<u>Kaitlin served 20 orders, Juan served 40 orders and Tony served 11 orders on Monday at the school cafeteria.</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Total of orders server at the school cafeteria by Kaitlin, Tony and Juan = 71
Tony served 9 orders fewer than Kaitlin
Juan served 2 times as many orders as Kaitlin
2. How many orders did each one serve?
For answering this question, we should prepare and write down our equation this way:
x = Number of orders served by Kaitlin
2x = Number of order served by Juan ( 2 times as many orders as Kaitlin)
x - 9 = Number of order served by Tony (9 orders fewer than Kaitlin)
x + 2x + x - 9 = 71
4x = 71 + 9
4x = 80
x = 80/4 = 20
x = 20 ⇒ 2x = 40 ⇒ x - 9 = 11
<u>Kaitlin served 20 orders, Juan served 40 orders and Tony served 11 orders on Monday at the school cafeteria.</u>
