22 Evaluate the expression for x = 2

jekas [21]

Answer:

22. 18

23. 10

Step-by-step explanation:

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

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
