Stephanie is bike-riding around her town. First she bikes to her friend's house, which is 2 miles west of her house. She then bikes to the deli, which is 2.5 miles southeast of her friend's house.
After that, she bikes north, directly back to her home. How many miles was her bike ride, in all?
2 miles
Friend's
House
Stephanie's
House
x miles
2.5 miles
Deli

Stephanie's bike ride in all is 6 miles

Step-by-step explanation:

The distance Stephanie rode her bike to her friend's house = 2 miles

The direction of Stephanie's friends house from her house = West

The distance Stephanie road to the deli South-East of her friend's house = 2.5 miles

Let 'x' represent the distance Stephanie bikes north back home from the deli

We have that Stephanie's path formed a right triangle

By Pythagoras's theorem, we have;

x = √(2.5² - 2²) = √2.25 = 1.5

x = 1.5 miles

Stephanie's bike ride in all  = (The distance Stephanie rode her bike to her friend's house) + (The distance Stephanie road to the deli South-East of her friend's house) + x

∴ Stephanie's bike ride in all  = 2 miles + 2.5 miles + 1.5 miles = 6 miles

Stephanie's bike ride in all = 6 miles

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
