a. rational
b. irrational
c. integer

B--rational

2. Evaluate 10 + .absolute value of 21 + x, -3
if x=9

37?

3. absolute value of -25, - (-32)

57

Answer 1

1. correct
2. not sure of your expression.
Do you mean 10 + │21+x│ - 3 ?
Why is there a comma after the x ?

If it is the way I assumed, then the value is 10 + 30 - 3 = 37 is correct.

3. is the absolute value around the whole thing ?
Again, why the comma ?

if it is │-25 - (-32)│
then │-25 + 32│
= │7│ = 7

if it is │-25│ - (-32)
then your answer is correct.
