Answer:
(x-5) (x-3)
Step-by-step explanation:
x^2 -8x +15
We want to know what numbers multiply to 15 and add to -8
-5 *-3 = 15
-5+-3 = -8
(x-5) (x-3)
It’s easy for the first one you add 10 each time
Your picture has several issues.
- x is not defined. It appears to be the number of apartments rented.
- R(x) is defined two different ways. The first way, it looks like it is the revenue from a single apartment. The second way, it looks like it is the revenue from the entire apartment complex.
- The derivative is in error. It should be -20x +2000. In any event, this is not the derivative you want. You're not trying to maximize revenue; you're trying to maximize profit.
- It might be useful to write an equation for profit: P(x) = R(x) -200x = -10x² +1800x. Then when you go to maximize it, your derivative will be P'(x) = 0 = -20x +1800 ⇒ x = 90.
Your answer is correct, but the path you followed to get there has a few potholes.
Well let's convert 2/3 to fraction of 6ths, by multiplying top and bottom by 2
Answer:
that could be any number
Step-by-step explanation:
There is not enough information to find out the exact amount so this could be any number.
