Answer:
Step-by-step explanation:
First, we will find the midpoint for the x - coordinate first.
Midpoint (x) = 
Now we will find the midpoint for the y - coordinate.
Midpoint (y) = 
Therefore from these 2 values we know that the midpoint of this 2 points is (-3.5,-0.5)
B because the multiplication has different signs
Answer:
2
- 5x² - 63
Step-by-step explanation:
Given
(2x² + 9)(x² - 7)
Each term in the second factor is multiplied by each term in the first factor, that is
2x² (x² - 7) + 9(x² - 7) ← distribute both parenthesis
= 2
- 14x² + 9x² - 63 ← collect like terms
= 2
- 5x² - 63
