Answer:

22. 18

23. 10

Step-by-step explanation:

22

  • you plug the number for the variable into the equation (3(2)²+6
  • order of operations say exponents first so you do 2²=4 so you have 3(4)+6
  • then you multiple 3•4=12 so 12+6
  • finally you add 12+6=18

23

  • plug in the number for the variable so 5–(-5)
  • so a negative and a minus will make it addition (negative + negative = positive)
  • do it is 5+5 which equals 10
