Answer:
A triangle is scalene if all of its sides have different lengths. A triangle is isosceles if two sides have equal measurements with each other. A triangle is equilateral if all three sides have equal measurements with each other. That is how you will explain it to your classmate
Step-by-step explanation:
Answer:Let x and (x-3) represent Elvira's and David's times respectively
D = r*t
Distances traveled are equal in this example***
14mph*x = 21mph(x-3)
solving for x
14x = 21x - 63
63 = 7x
x = 9hr, the time that Elvira traveled. David traveled 6hrs (9hr-3hr = 6hr)
CHECKING our Answer***
14mph*9hr = 126mi = 21mph*6hr = 126mi
Step-by-step explanation:
Monomial to the 2nd degree
