Answer:
Taking that you didn't provide any other information about the values of x..
The only plausible answer, which probably isn't your case but still can be valid out of context is 19.
Step-by-step explanation:
"X" is 10 in Roman numbers.
9 + 10 = 19
(But I suppose that you had more details to the question that you didn't yet share :) )
OR.. the answer might be an algebraic expression..
<u><em>"9+x" years old.</em></u>
Eliminate parenthesis by using the distribution property
= 5x² -3x +3 - x² - 2x +1
Group similar terms
= (5-1)*x² + (-3 -2)*x + (3+1)
Then sum everything:
= 4x² -5x +4
(0,5) when you graph it these will be your point you can use desmos which is a graphing calculator
When you multiply the numerator and denominator by the same number, you get an equivilent fraction
