Answer:

Step-by-step explanation:

(x+6)(x+4)(x-3)

= [(x+6)(x+4)](x-3)

= (x² + 4x + 6x + 24)(x - 3)

= (x² +10x + 24)(x - 3)

= x³ - 3x² + 10x² - 30x + 24x - 72

= x³ + 7x² - 6x - 72

Answer:

x^3 +7x^2 - 6x - 72.

Step-by-step explanation:

(x + 6)(x + 4)(x - 3)

= (x + 6)[x(x - 3) + 4(x - 3)]

= (x + 6)(x^2 - 3x + 4x - 12)

= (x + 6)(x^2 + x - 12)

= x(x^2 + x - 12) + 6(x^2 + x - 12)

= x^3 + x^2 - 12x + 6x^2+ 6x - 72

= x^3 +7x^2 - 6x - 72.

This is geometry.. If lines l and M are parallel than we look at the line that goes from bottom left to the top right. this is called the transversal. When lines are parallel then alternate interior angles are congruent. That means opposite sides of the transversal and inside the parallel lines. That means 28 and  are congruent.

Your answer is 28..  I hope I helped you learn something..
