Question

(im going point broke after this plsssssssssssss HELP))Minnie organizes data in a table to show the net change in the number of people subscribing and unsubscribing to her website each month.

Month 1 2 3 4 5 6 7 8 9 10
Change −11 17 −1 −1 −1 −1 −11 17 −11 −11
She writes the sum of the ten integers, then factors her expression.

She correctly determines the total change for the 10 months.

What factored expression does she write, and what is her answer?

Answer 1

-14

Explanation:

Find out how many times (-11) , (-1) and 17 appears.

(-11) is four times and (-1) is four time.

4 * (-1) + 4 * (-11) = 4 * (-1 - 11)

17 is appearing two times.

2*17

Now, the expression is,

4 * (-1 - 11) + 2 *17

4 * (-1 - 11) + 2 *17 = 4 *(-12) + 34

= - 48 + 34

= -14
