Line segment AB and CD both are congruent with the length of 16 units.
We have been given two line segment AB and CD of whose coordinates are :
A = -7 , B = 9 and C = -4 , D = 12
The distance formula is given as |x2 – x1|
Therefore the length of AB = |9 – (-7)|
= 9 + 7
= 16
The length of CD = |12-(-4)|
= 12 + 4
= 16
Note that when two line segments are congruent then their distance is equal.
Thus both the line segment AB and CD are congruent with a length 16 unit.

the answer is 138, because you divide first then add and then multiply.
The amount spent is an illustration of subtraction and proportions
The amount left in his earnings is $414.25
<h3>How to determine the amount left in his earnings?</h3>
The given parameters are:
Rate = $22 per hour
Time = 40 hours
So, the total earnings is:
Total = $22 * 40
Evaluate
Total = $880
He spent half on bills.
So, we have:
Bills = 0.5 * $880
Bills = $440
He buys a video game for $25.75
So, the amount left is
Amount left = $880 - $440 - $25.75
Amount left = $414.25
Hence, the amount left in his earnings is $414.25
