Simplify the equation by combining like terms:

7x²+ 4x - x²

Solve:

7x²+ 4x - x²

7x² and -x² are like terms, so combine them.

6x² + 4x

There are no more like terms, so your answer would be: 6x² + 4x

Answer:

6x² + 4x

Help plzzzzz help me

Answer: 10 < x < 60, or x is from 10 to 60

Step-by-step explanation: A domain of a graph consists of all of the input values shown on the x-axis while the range consists of all of the output values shown on the y-axis. Since the question asks to find the domain, you should look at the values of the graph from left to right. The domain includes all real numbers. Notice the black horizontal line on the graph and match up the beginning of it and the end of it with the values on the x-axis. The line begins at an x-value of 10 and ends at an x-value of 60; therefore, the domain (x-values) is from 10 to 60.
