Yes you use the method of your choice to solve (x+7)*(x+7)
Then you distribute the negative -1(x^2+14x+49)

-x^2-14x-45 should be your answer

Answer:

We have to put the data for purchased item in a frequency table.

Step-by-step explanation:

The diagram is attached below.

Firstly we have to see that how many customers fall under range 0 to 5.

Then 5 to 10.

Then 10 to 15.

Finally

15 to 20.

If we go through the items purchased by customers we can see that item ranges from 0 to 5 have 4 customers.

Item purchased range from 5 to 10 have 2 customers.

Item purchased range from 10 to 15 have 7 customers.

Item purchased range from 15 to 20 have 1 customers.

Total number of customers = 14

As we have total 14 number of customers and they have varied quantity of items purchased.
