Distance :
Midpoint :
x (m) = (2+9)/2 = 11/2
y (m) = (-14-9)/2 = -23/2
M (11/2, -23/2)
Answer:
see explanation
Step-by-step explanation:
Given
9 - 225
← factor out 9 from each term
= 9( - 25
) ← difference of squares
Difference of squares factors in general as
a² - b² = (a - b)(a + b)
= (x² )² ⇒ a = x²
25 = (5
)² ⇒ b = 5
Hence
- 25
= ( -5
)(
+ 5
)
Thus
9 - 225
= 9 ( - 5
)(
+ 5
)
