For this case we have the following functions:

The first thing we must do is calculate the sum of functions or equivalently:

We have then:

To complete the sum, we must add the terms whose exponents are equal.
We have then:

Then, we evaluate the function for x = 2:

Rewriting we have:

Answer:
Variables in Mathematical Expressions. In algebra, we begin to see variables, or letters that are used to represent numbers. An example of a mathematical expression with a variable is 2x + 3. All variables must have a coefficient, a number that is multiplied by the variable. Please give me the brainliest answer?
:) Hoped this helped!!! Have a good day!!! <3
Answer:
1. Change each number to an improper fraction.
2. Simplify if possible.
3. Multiply the numerators and then the denominators.
4. Put answer in lowest terms.
Step-by-step explanation:
Number of players=85
percent of left handed players=20%
85*20/100=
simplify that:
85*1/5=
simplify again:
85*5= 17
17 players are left handed.
Hope that helps!!
Have a wonderful day!!
