Hi, this is the notation for inclusion of all real
numbers.
We can also state numbers which are positive or negative with a sign on top of the R notation like so:
Answer: O x= -1 or x = 6
Step-by-step explanation:
So what you do for distributive property is take #1 for example: 3(2x + 10) = 54. When there’s a parenthesis, you take the outside number which is the 3 times the numbers inside the parenthesis. So after doing that first step you should get 6x + 30 = 54. Now you want to get rid of the 30 so you do 30-30=0 but you have to do it on the other side as well. So subtracting 30 on both sides you should have 6x = 24. Now you want to get x by itself. The opposite of multiplying is dividing so you divide 6 from 6x. So the same on the other side. You get your answer x=4 if you did everything correct
Step-by-step explanation:
The answer will be 9 I hope this help you
