Determine whether each expression is equivalent to or not equivalent to 5.7+9d.

6.8+(−2.5+11.5)d−1.1

(8.5d+0.5)+5.7

1.9+4.3d+3.8+4.7d

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|

noncoplanar points are points that do not lie on the same line.
