Answer:7m^5 - 3m^3 + 9
Step-by-step explanation: You’d have to remove the brackets, but remember that the second has to have everything multiplied by -1, because there’s a minus sign in front of the second bracket. Then you’d group like terms, then add or subtract. Here’s the step by step
6m^5 + 3 - m^3 - 4m + m^5 - 2m^3 + 4m + 6
2. 6m^5 + m^5 - 2m^3 - m^3 + 4m - 4m + 6 + 3
Subtract or add what’s needed, which would be figures with the same variable and coefficient.
3. 7m^5 - 3m^3 + 9
After this, there’s nothing you can add, since the remaining figures don’t have the same variable.
Hope it’s clear and this wasn’t that long
For number 6, Tom's unit rate was 0.1254 per meter. Samma's unit rate 0.1299 per meter. So Samma had a faster unit rate by 0.0045.
For number 8:
$10.45 ÷ 5 = $2.90
So the unit rate is $2.90.
Hope this helps. :)

range:
![( - \infty ,4]](https://tex.z-dn.net/?f=%28%20-%20%20%5Cinfty%20%2C4%5D)
equation:

Step-by-step explanation:
domain is all X values and the X values will extent till infinity in both negative and positive direction, the range is all y values and the y value will go from negative infinity all the way to 4, where the graph stops.
Answer:
y = 30m and x = 1 h
