Standard form. х + 9 х + 3​

10x+3, or 2x+12, or +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 +12x+27.
