Lines l and m are intersected by transversal t and l // m. If m

angle 7 is 112

Step-by-step explanation:

angles 2 and 6 are congruent, and vertical angles are also congruent, so you know that angles 2 and 7 have the same value

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
