•how do you use the distance formula and slope formula to classify a triangle?

To classify the angle of a triangle (acute, obtuse, or right), you can use slope formula to see if the slopes are perpendicular. If so, it is a right triangle. The distance formula can be applied to figure out whether the triangle is isosceles, equilateral, or scalene. if the triangle is isosceles, then two of the sides will be the same length and one side will be of a different length. If the triangle is equilateral, then all sides will be of the same length. If the triangle is scalene, then all side will be of different lengths.

Ithink the answer is c just trying to others

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
