Which is a correct factorization of 391? a.(20 - 3)2 b.(20 - 3)(20 + 3) c.(20 - 9)(20 + 9) d.(20 + 3)2

The answer is option B.

Because (20 - 3) (20 + 3)

= (20)^2 - 3^2

=400 - 9

=391.

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
