How many raisins are left in a jar of 91 raisins after you have eaten some? let r= amount of raisins left; n = amount of raisins eaten

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

if the angular bisector of an triangle bisects the opposite side, prove that the other two sides are equal.
