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
Answer:
B) y=12x
Step-by-step explanation:
We are given with the coordinates 
Where 
represents the number of days.
represents the number of likes she got.
To model the equation using Kyle's data we find the slope using the given coordinate.
Let us say 
and 
Slope 
formula , 
Plug in the above points now, we get
Now we use the point-slope formula, 
Plugging the corresponding values.
Thus option is B is the correct answer.
Answer:
width= 6
Step-by-step explanation:
equation: 50=2(2w-5)+ 2w w= width
50=6w-10
60=6w
w=6
