Abird leaves its nest and flies 10 km due west. the bird then flies 19 km due north. what is the shortest distance from the bird to its nest? round to the nearest tenth of a km.

21.5 km

Step-by-step explanation:

Pythagorean Theorem: shortest distance is hypotenuse

Legs: 10 km, 19 km

10^2+19^2=c^2

100+361=c^2

c=sqrt(461) = 21.4709105535838885 approx. 21.5

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
