1, when you factor you get 6x(x^2-1)+4(x^2-1)=
1/2 (Base x height) = area
1/2 (4*x)=10
2x=10
X=5
The height is 5 units
M= -6/5
hope this helped!!
In order to find this you have to set i by itself first we will subtravt 40 from both sides(because 40 is s positive and in order to get rid of a positive you have to use a negative) now we have -40=5i, now divide 5 from both sides to get i=-8, that is what Terry will be givng from tip
Hope this helps
