Answer:
21+/-sqrt(253)=x
So one value for x is 21+sqrt(253)
and another is 21-sqrt(253)
Problem:
Given (21,7) and (x,1), find all x such that the distance between these two points is 17.
Step-by-step explanation:
Change in x is x-21
Change in y is 7-1=6
distance^2=(change in x)^2+(change in y)^2
17^2=(x-21)^2+(6)^2
289=(x-21)^2+36
Subtract 36 on both sides:
289-36=(x-21)^2
253=(x-21)^2
Take square root of both sides:
+/-sqrt(253)=x-21
Add 21 on both sides:
21+/-sqrt(253)=x
Answer:
60 miles
Step-by-step explanation:
Jake is traveling at 12 miles per hour
That means, every hour that he travels on the boat, he travels 12 miles
So after 5 hours, he must have traveled 12 miles 5 times
Solve:
- 12mph for 5 hours
- 12 * 5
- 60 miles
He traveled 60 miles

<span>Given the proportion a/b = c/d, the extremes are a and d.
The means are b and c.
To remember this, think about the terms of the proportion as being in order:
a, b, c, d. On the ends are a and d and are the extremes. Between the extremes are the means, b and c.</span>
