Step-by-step explanation:
hope this helped :)
(3x^2-2x+4)+(5x^2+6x-8) - Combine like terms
8x^2+4x-4
(f+g)(x)=8x^2+4x-4
For example let's say Megan has to pay the cab driver $50. Here's the equation 50=1.50x + 5
First you want to get x by itself on one side. So subtract 5 on both sides
50=1.50x + 5
-5 -5
---------------------------
45=1.50x
Now that you have x on one side; however, you want to divide to get the answer.
45=1.50x
-----------------------
1.50
x = 30
So if Megan pay $50 that mean she rode 30 miles

Answer:
36 blocks.
Step-by-step explanation:
We have been given that Mikaela travels 15 blocks on her skateboard in 5 minutes. We are asked to find the number of blocks that she can travel on her skateboard in 12 minutes.
We will use proportions to solve our given problem.
Therefore, Mikaela will travel 36 blocks on her skateboard in 12 minutes.
<u>Solution-</u>
The equation given here,
But, at x=1, 
becomes infinity so it can't be a solution to the equation.
∴ x=1 is the extraneous solution of the equation
