Point m is the midpoint of ab . am=3x+3, and ab=8x−6. what is the length of am ?

As given m is a midpoint of ab. So am is half of ab.

So we can write



As given am = 3x+3 , ab = 8x - 6.

So









So x = 6.

So length of am = 3x+3 = 3*6 + 3 = 21

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
