Answer:
Step-by-step explanation:
18y
32m = 8m · 4
56mp = 8m · 7p
32m + 56mp = 8m(4 + 7p)
Answer:
x = -2, -5 where -2 is a double root
Step-by-step explanation:
The real roots are the solutions to the cubic equation. You find them by setting each factor equal to 0 and solving for x.


Since -2 appears twice, it is a double root.
If l and m are parallel, then ∠1 must measure 55°.
The addition of the angles of a triangle is equal to 180°, in consequence,
