Find the distance between the pair of points. (17.-6) and (7.-12)

Using the distance formula:-

Distance  = square root [ (17 -7)^2 + (-6 - -12)^2 ]

= square root (  136)

= 11.66 answer

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
