It could be an example of The level of its pH
3(4x + 6) - 9x
Apply the Distributive Property:
3 (4x) + 3 * 6 - 9x
Multiply by 4 by 3 to get 12:
12x + 3 * 6 -9x
Multiply 3 by 6 to get 18:
12x + 18 - 9x
Subtract 9x from 12x to get 3x:
3x + 18
Your answer is the second option!
Answer:
180 or 150
Step-by-step explanation:
good luck my friend
–(x^2–2x+12) would become –x^2+2x–12.
3x^2+9x+13 – x^2+2x–12
= 2x^2 + 11x – 1
