<u>Complete Question:</u>
A car dealership has 24ft of dividers with which to enclose a rectangular play space in a corner of a customer lounge. The sides against the wall require no partition. Suppose the play space is x feet long.
A) express the area of the play space as a function of x
B) find the domain of the function
Solution:
A)
The rectangle has area of length * width
length is x
so width will be 24 - x
Hence, the area will be:
Area = x(24 - x)
Area = 
B)
Domain is the set of x values that make the function defined.
The domain will be all values less than 24.
Because if you take 24, the area would be 0 [doesn't make sense]
if you take anything over 24, the area would be negative [not possible]
Hence, the domain is:
Domain = {x < 24}
Answer: 60
Step-by-step explanation:
75% of 80 is 60.
Multiply 80 by .75 to get the answer.
3x - 12
3(3x/3 - 12/3)
3(x - 4)
The answer is: 3(x - 4).
A: Deena subtracted 25, instead of adding it.
B: 9x - 25 = 88.
C: no idea
