<h2>Answer:</h2>

Look just replace the n's with -1.

<h2>Step-by-step explanation:</h2>

So, it will look something that's close to this.

17n – 5n2 + 2n3; n = -1

17(-1) – 5(-1)2 + 2(-1)3

Then evaluate.

How does -1.125 + 1.2 = 0.075 instead of 0.925?
kenny6666 [7]

Answer:

.0075 (hope this help; let me know if not)

Step-by-step explanation:

The operation is + and the signs of the numbers are opposite so we have to subtract. The bigger number has positive sign in front if so we do 1.2-1.125=1.200-1.125

I'm going to line up

1.200

-1.125

---------

If you have 200 and you take about 125... 75 should beleft

so

1.200

-1.125

---------

0.075
