Parallel to y=-1/4x-12 through (12,10)

yes

step-by-step explanation:

yes

(1 km=1000m, 1m=100 cm)

using the formula for pythagorean theorem (a2+b2=c2)(the twos are exponents), and knowing that you have b squared and c squared, just reverse it. 26 squared minus 10 squared equals c squared. 26 squared is 676 and 10 squared is 100. you get 576, then use your square roots to undo the squared numbers to get 24.
