Which expressions below equal a rational number? choose all that apply.

Labeling the options from 1 to 5, going from top to bottom , to make the answer more easier to type: 4,5

Step-by-step explanation:

1) Not rational

Why: Pi is not a rational number

2)Not Rational

Why: 7/9(the sum of to the equation) goes on forever

3)Not Rational

Why: 5√5 or √125(sum of equation) is not a whole number and goes on forever

4)Rational

Why: (√17+12)-(√17-6) = 18, a rational number

You multiply -1 (subtraction signs always

refer to -1 when there is not other in front of

the parenthesis) to √17-6 in order to get rid of

parenthesis

You add the common variables together

√17+12-√17+6=18

the √17s cancel each other out

5)Rational

Why: √2•√2 is √4 which equals to 2,-2, these are rational whole numbers

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
