Answer:

14x + x^2

------------------

9x^2

Step-by-step explanation:

2x /x^2 + (x-4)/ 9x

Cancel the common factor of x in the first term

2 /x + (x-4)/ 9x

We need a common denominator of 9x

2 /x *9/9 + (x-4)/ 9x

18/9x  + (x-4)/9x

Add the numerators

18+x-4

--------------

9x

14+x

----------

9x

Multiply the top and bottom by x to get it to match one of the answers

14x + x^2

------------------

9x^2

A new club sent out 288 coupons to boost sales for next year's memberships. They provided 5 times as many to potential members t
Aliun [14]

Answer:

D. 48

Step-by-step explanation:

We don't know the numbers of coupons sent to existing members and to potential members, but we know a relationship between the number.

They sent 5 times as many coupons to potential members as they did to existing members.

Let x = number of coupons sent to existing members.

Then 5x = number of coupons sent to potential members.

The total number of coupons sent was x + 5x = 6x

The total number of coupons sent was 288.

Therefore, 6x must equal 288 giving us an equation with a single variable.

6x = 288

x = 48

Answer: 48

Select the statement that correctly describes the expression below
Kitty [74]

Answer:

B

Step-by-step explanation:

The equation is (2x+5)^2.

It can't be A because 2 is the multiplier for only x.

It can't be C because the square is outside of the equation.

It can't be D because again, the square is outside of the equation.

So the only thing left is B.

Hope this helped!
