What is the answer when you see this?
"x + x + 2x"
Does it become 2x^3?
No. You're not multiplying; you're adding.
x + x + 2x = 4x
Great. Thank you, Ms. Sue.
You're welcome. :-)
To find the answer to the expression "x + x + 2x", we can simplify it by combining like terms. Like terms are terms that have the same variable(s) raised to the same exponent(s).
In this case, all of the terms have the variable "x" raised to the power of 1. So, we can combine the coefficients of these terms.
The coefficients are the numbers multiplying the variable "x". In this expression, the first "x" has a coefficient of 1, the second "x" also has a coefficient of 1, and the "2x" has a coefficient of 2.
When we combine the coefficients, we get:
1 + 1 + 2 = 4
Therefore, the simplified expression is 4x.
It does not become 2x^3 because there are no exponents involved in this expression, and combining like terms only involves adding or subtracting coefficients when the variables and exponents are the same.
