The easiest way to find the expansion of the expression given would e to distribute. To distribute, you have to multiply each of the terms in the parentheses by 9. The expansion of the expression would be 9x + 18.
9 (x + 2)
9 · x = 9x
9 · 2 = 18
9x + 18
Hope this helps. Good luck! :)
Answer:1/3(9) no problem dawg
Step-by-step explanation:
Answer:
x = 20/9
Step-by-step explanation:
We want to write out all of the mixed fractions into improper fraction form. So -2 and 1/9 becomes -19/9 and -4 and 1/3 becomes -13/3. Then we get (-19/9) - (-13/3). The two minus signs together means a positive/plus sign, so we get -19/9 + 13/3. In order to add, we want the denominator to be the same. A common denominator could be 9, so -19/9 + 13(3)/3(3) = -19/9 + 39/9 = 20/9, which is our final answer
