Answer:
The dimensions of the mirror is 9 feet and 2 feet
Step-by-step explanation:
Keep in mind that the area and perimeter of a rectangle is:
Area - length x width
Perimeter - 2 (l + w)
List the factors of 18 (the area of the mirror):
1, 2, 3, 6, 9, 18
POSSIBLE DIMENSIONS OF MIRROR:
1 ft and 18 ft
Area = 18 ft^2
Perimeter = 38 feet
2 ft and 9 ft
Area = 18 ft^2
Perimeter = 22 feet
3 ft and 6 ft
Perimeter = 18 feet
The rectangle with dimensions 2 feet and 9 feet corresponds with the area and perimeter of the mirror mentioned. So those are the correct dimensions.
Hope these helps!

Answer:
(a) They should sell 78 pizzas to receive the bonus
(b) 7.69 % decrease
Step-by-step explanation:
(a) The number of pizzas the owner wants to see sold is 65 plus 20% of 65
We can calculate 20% of 65 by multiplying the decimal form of 20% (0.2) times 65. That is: 
. This means that the owner wants to sell 65 + 13 = 78 pizzas today.
(b) If the actual number of pizzas sold was 60, the reality is that the number of pizzas sold decreased (from 65 to 60). We can therefore calculate the percent of decrease as:
%
We can round this percent number to its nearest hundredth as: 7.69 %
