3x^2-n-4y^2=(3x-y)(x+4y),n=? need asap f.11xy g.-11xy h.13xy j.-13xy

n = -11xy, so the answer is G.

Step-by-step explanation:

3x^2−n−4y^2=(3x−y)(x+4y)

Step 1: Add -3x^2 to both sides.

3x^2−4y^2−n+−3x^2=3x^2+11xy−4y^2+−3x^2

−4y^2−n=11xy−4y^2

Step 2: Add 4y^2 to both sides.

−4y^2−n+4y^2=11xy−4y^2+4y^2

−n=11xy

Step 3: Divide both sides by -1.

n=−11xy

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

they share a side

step-by-step explanation:

this is the fundamental definition of adjacent angles

they:

1) share a vertex

2) share a side.
