TheThe best approximation for the perimeter of polygon ABCDE is: C. 24.3 units.
<h3>Perimeter of polygon</h3>
Coordinate:
A=(-2,3)
B=(0,6)
C=(5,4)
D=(4,-1)
E=(-1,-2)
Distance AB=√(0+2)²+(6-3)²
Distance AB=√4+9
Distance AB=√13
Distance BC=√(5-0)²+(4-6)²
Distance BC=√25+4
Distance BC=√29
Distance CD=√(4-5)²+(-1-4)²
Distance CD=√1+25
Distance CD=√26
Distance DE=√(-1-4)²+(-2+1)²
Distance DE=√25+1
Distance DE=√26
Distance EA=√(-2+1)²+(3+2)²
Distance EA=√1+25
Distance EA=√26
Perimeter of pathogen ABCDE
=AB+BC+CD+DE+EA
=√13+√29+√26+√26+√26
=√13+√29+3√26
=24.2877 units
= 24.3 units (Approximately)
Therefore the correct option is C.

Answer:
of what? i know how to do these but tell me the equation
Step-by-step explanation:
you asked a very not telling question. need more info to give an answer
Gotcha.
We know Sean spent 15 more minutes than Faith.
So, we know this to be true:
Sean = 15 + Faith
We also know that Sean and Faith spent a TOTAL time of 55 minutes on homework.
So, we have this:
Sean + Faith = 55
We can solve for Faith's time spent in homework now since we have two equations.
Here are the two equations we have:
Sean = 15 + Faith
Sean + Faith = 55
To make solving for Faith easier, I'm going to rearrange the second equation to this:
55 = Sean + Faith
Now, we solve the problem.
Sean = 15 + Faith
55 = Sean + Faith
We know what Sean is, he is 15 + Faith.
So, we can plug in 15 + Faith into Sean in the second equation.
55 = 15 + Faith + Faith
Simplify:
55 = 15 + 2Faith
55 - 15 = 15 - 15 + 2Faith
(I subtracted 15 from both sides)
40 = 2Faith
Now, divide by 2 on both sides to get Faith's time.
40 ÷ 2 = 2Faith ÷ 2
20 = Faith
