Answer:
x³ + 7x² - 6x - 72
Step-by-step explanation:
Given
(x + 6)(x + 4)(x - 3) ← expand the second and third factor, that is
(x + 4)(x - 3)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x - 3) + 4(x - 3) ← distribute both parenthesis
= x² - 3x + 4x - 12 ← collect like terms
= x² + x - 12
Now multiply this by (x + 6) in the same way
(x + 6)(x² + x - 12)
= x(x² + x - 12) + 6(x² + x - 12) ← distribute both parenthesis
= x³ + x² - 12x + 6x² + 6x - 72 ← collect like terms
= x³ + 7x² - 6x - 72
GOOD LUCK CHUCK:))))))))

Step-by-step explanation:
However, you're missing a factor of 9.
Answer:
1. linear pair (c and d)
2. alternate interior angles (c and f)
Step-by-step explanation:
Here, we want to get the relationship between angles
From what we have , we can see that angle d and angle c lie on a straight line
Thus, we have that angle c and angle d are supplementary angles since they will add up to give 180 degrees . So we can call the two a linear pair
For c and f, we can notice a z-like angle between the two
In this case, when we have a z-like angle, the relationship that exists between the two angles is that they are alternate interior angles
