Hi guys :) how is your day

Need on this geometry question. explain how you did it.

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =

Solve for x where 0 equation: cot^2x+2cotx+1=0
