Answer: add all the sides up 20+2+2+11+3.14
Step-by-step explanation:
Distance = √[(-12 - 11)^2 +(-4 - (-4))^2]
= √(529+0)
= 23
answer
<span>length of the line segment = 23</span>
It's important to study and study. I recommend studying the homework or study sheet the day before the test. Most likely the teacher has added a similar problem on to the test. Add a friend to help you study.
To make it fun, buy candy and quiz yourself or friends!
If you get a problem right, them give yourself candy.
