Sadie painted a square tile that has an area of 23 ft squared. What is the approximate length, to the nearest tenth of one side of the tile?

20 i think

Step-by-step explanation:

i think 20 because if its 23, and if its 25 (in the middle), you would round up.. but since its 7 numbers closer to 20 instead of 30, it should be 20.

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|
