I think it is 280 cubic inches: the triangle would be the base, so area would be 1/2(7x10)= 35
Take that area times the height of 8 and you get 280.
We have
−x²<span> − 3x − 1 = −x − 4
let
f(x)=</span>−x² − 3x − 1
g(x)= −x − 4
the solution for
f(x)=g(x) is the intersection both graphs
using a graph tool
see the attached figure
the solution are the points
(-3,-1)
and
(1,-5)
X^2+8x+19+39/(x-2)
I cant show how to use synthetic unless I attach a file
