Answer:
10x+3, or 2x+12, or [tex]x^{2}[/tex]+12x+27
Step-by-step explanation:
If the equation is x + 9x + 3, combine like terms you get 10x+3
If the equation is x+9 + x+3, combine x and numbers (like terms) and you get 2x+12
If the equation is (x+9)(x+3) or it is asking you to multiply, multiply x by x, and 9 by x, and 3 by x, and 9 by 3. Add them all up (like terms) and you get [tex]x^{2}[/tex]+12x+27.
Let me know which one you meant, and if its correct and have a great day! Please give brainliest if you can.
