Step 2: Subtract exponents
You should get 3² because of exponent rules. Remember when you multiply exponents you add the powers and when you divide exponents you subtract the powers.
Answer:
1. -10x^2-x+6-10x 2-x+6 = -10x^2 - 22x + 12
2. 10x^2-510x 2-5 = 10x^2 - 1020x - 5

First apply the exponent: 3 ^ 2
9
Then we do the multiplication: 4 * 9 = 36
Finally we add
8 + 36 = 44
All you need to do is add the miles from Eaton to Baxter and from Baxter to Wellington to get your answer...
42 + 37 = 79 Now we need to add the fractions

To add we need a
common denominator. 2 and 5 can both go into 10, so that will be a our common denominator.
Now you have...
which is equal to 
add that to the 79 we got earlier ...
The toal and final answer is
miles !Hope I helped and remember to vote this as the brainliest answer ! :)
