The answer is 14x.
You always have to do whats in the parenthesis first. In this case you would do 7 + x = 7x. Then, you add this 7x to the other 7 x. 7x+7x=14x.
Step-by-step explanation:
A case of paper cups costs $408 / 17 = $24.
5 more cases => 22 cases of paper cups total.
Hence the total cost will be 22 * $24 = $528.
The domain of the function is

<h3>How to determine the domain and the restrictions?</h3>
The attached image represents the complete form of the question
The functions are given as:
![f(x) = \sqrt[3]{3x}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Csqrt%5B3%5D%7B3x%7D)
g(x) = 5x + 2
The function (f/g)(x) is calculated using:

This gives
![(\frac{f}{g})(x) = \frac{\sqrt[3]{3x}}{5x + 2}](https://tex.z-dn.net/?f=%28%5Cfrac%7Bf%7D%7Bg%7D%29%28x%29%20%3D%20%5Cfrac%7B%5Csqrt%5B3%5D%7B3x%7D%7D%7B5x%20%2B%202%7D)
The denominator cannot be 0.
So, we have:

Solve for x

Hence, the domain of the function is

Answer:
6.5 %
Step-by-step explanation:
The simple interest formula is
I = Prt
Data:
I = $1755
P = $3000
t = 9 yr
Calculation:
1755 = 3000 × r × 9
1755 = 27 000 r
Divide each side by 27 000
r = 1755/27 000 = 0.065 = 6.5 % APR
The annual percentage rate was 6.5 %.
Answer:
Step-by-step explanation:
Integers with a product of 567 are ...
567 = 1·567 = 3·189 = 7·81 = 9·63 = 21·27
The last of these pairs of factors have a difference of 6, so they are the answers.
Jackie's number is 27; Adrian's number is 21.
_____
You could let "a" represent Adrian's number and write the equation ...
a(a +6) = 567
a^2 +6a +9 = 576 . . . . . complete the square
(a +3)^2 = 24^2 . . . . . . . write as squares
a = -3 +24 = 21 . . . . . . . . take the positive square root; subtract 3
Adrian's number is 21; Jackie's number is 27.
