List the factors:
21: 1, 3, 7, 21
40: 1, 2, 4, 5, 8, 10, 20, 40
They only have 1 in common.
So 1 is the greatest common factor.
If the square and equilateral triangle have the same side length, a square would have a larger area.
Use these are equations and you can see which one is greater.
Square area with side length s: s^2
Equilateral triangle area: s^2 * (√3 ) / 4
(√3) / 4 < 1, if you didn't know
I hope this helps. Have an awesome day! :)
To answer question 8.0% i had the same one i'm pretty sure it correct
So a mile has 5280 feet.
21,129/5280= 4 mph
multiply
4 x 2 = 8 miles in 2 hours
