Can i get some plzz i really need to finish this

9. a) 8.25

10. c) 180

9) 8.25 - Option A

10) 180 - Option C

Step-by-step explanation:

9) The square root of 68: To solve this you need to look for the closest square root before and after 68. This is 64 which is 8 and 81 which is 9.

Then you calculate how far apart they are: 68 - 64 = 4 and 81 - 64 = 17

Finally, since 68 is closer to 64 you approximate which gives you 8.25

10) Least common multiple or LCM is the smallest number that can be divided by all 3 numbers:

12 - 1, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180,

15 - 1, 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180

18 - 1, 18, 36, 54, 72, 90, 108, 126, 144, 162, 180

So since 180 is the smallest number that can be divide by all three numbers that is the least common multiple.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

none.

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
