Compare the values they have given you with the diagram. a, b and c are all sides of the triangle they want you to find the perimeter of. Knowing this, all you have to do is add a, b and c. h is not important because you don't count the altitude of a triangle when you calculate perimeter.
12 + 10 + 12 = 34
The perimeter of the triangle is 34 ft.
Slope = (y2-y1)/(x2-x1)
(3+1)/(2-0) = 4/2 = 2
The slope is 2
10/7 or just over one salt lick
2/7 salt licks per horse
So 2/7 * 5 horses is 10/7
Crown please
She can bake 48 muffins in 90 minutes. Since she can bake 24 in 45 min, 90 min is double that, so double the original amount of cupcakes. 24x2=48
