You are going to treat this as a triangle so one side is 13 units long and the other is 22. And using the pythagorean theorem a²+b²=c².
13²+22²=c²
169+484=c²
653=c²
√653=√c²
25.55386...=c
Or, rounded to the nearest hundredth, 25.55
Answer:
5(2x-8)+15=-15
10x-40+15=-15
10x-25=-15
+25 +25 (add 25 to both sides)
____________
10x=10
divide by 10 on both sides
x=1
Answer:
10.48 miles.
Step-by-step explanation:
That is 4/5 * 13.1
= 10.48 miles.
A = 1
b = -2
c = -3
And when you plug in and solve you'll get correct answers of x = 3 and x = -1
