Answer:
3n^2-5n-28
Step-by-step explanation:
FOIL: first inside outside last
Add together the products of the first two parts (n*3n=3n^2), the outer two parts (n*7=7n), the inner two parts (-4*3n=-12n), and the last two parts (-4*7=-28). Simplify, and your answer is 3n^2-5n-28.
3n^2 - 5n - 28
(n - 4)(3n + 7)
3n^2 + 7n - 12n - 28
hope this hepls!!!
a no the corresponding angles are not congruent
∠A ≠ ∠E and ∠D ≠ ∠H
