Answer:
The answer would be 46x
Step-by-step explanation:
-2x+13=11
-7x+28=35
46x
The expression (-4x + 9)^2 cannot be equal to (-4x)^2 + 9^2 because it is actually equal to the product of two factors (3 + 2sqrt x) (3- 2 sqrt x). One cannot use obviously distributive property. Hence the answer to this problem should be C. as she did not understand both perfect square trinomial and did not determine the product
Answer:
2 3/4
Step-by-step explanation:
2=2
.75= 3/4
Example 75 cents is equal to 3 quarters
The revenue function is,

For maximum and minimum value, the first derivative of function is equal to 0.
Determine the first derivative of revenue function.

For maximum and minimum value, R'(x) = 0. So

Since x = 700 corresponds to maximum or minimum value of revenue.
Determine the second derivative of revenue function.

Since second derivative of revenue function is less than 0 for every value of x. So x = 700 corresponds to maximum value of revenue.
So 700 villas rented to produce maximum revenue.
Answer: 700 villas
