Step-by-step explanation:
Hey You seem don't understand the Rational numbers and Irrational numbers
I will give you the example here
Irrational numbers are the numbers that has des keep going forever, like Pi,
will but keep going forever and has NO PARTERN. if it was like 1.4141414141414141414141414..... thats not a Irational numbers
where Rational number are like: 1,3,-1,7/10......
40/2=20 half is as many their is if she has lest of seven round to the highest num because they are all even numbers
By rearranging your terms!
1) First, remove the parentheses.
2x+5+3x-12
2) Next rearrange like terms together
2x+3x+5+(-12)
3) Now combine like terms!
2x+3x= 5x
5 +(-12)= -7
4) Final answer: 5x+(-7)
