To get from the post office to the library, sindy walked due north and then due east. the distance sindy walked east is 20 meters more than the distance she walked north. if sindy were able to walk directly from the post office to the library in a straight line, she would have walked 150 meters. suppose x represents the distance sindy walked north. which equation can be used to find x?
x^2+(x+20)^2=150^2
202=x^2-150^2
x+(x+20)=150
x^2+(x+150)^2=20^2

If its non of them tell me..valerie took a day-trip. she drove from her house for a while and took a coffee break. after her coffee break, she continued driving. after  2  hours of driving after her coffee break, her distance from her house was  210  miles. her average speed during the whole trip was  60  miles per hour.valerie created the equation  y−210=60(x−2)  to represent this situation, where  xx  represents the time in hours from her coffee break and  yy  represents the distance in miles from her house.which graph correctly represents valerie's distance from her house after her coffee break?
