Answer:
7) 72
8) ( 2, -5/3 ) and ( 0, -7/3 )
9) ( -2, 0 )
Hope this helps you.
Step-by-step explanation:
7)
8) A = (4,-1) and B = (-2,-3)
Points of trisection are at:
- (2A+B)/3 = ( (8-2)/3, (-2-3)/3 ) = ( 2, -5/3 )
- (A+2B)/3 = ( (4-4)/3, (-1-6)/3 ) = ( 0, -7/3 )
9) Let the point be (x,0).
Then equidistant from (-2,5) and (2,-3)
=> (x+2)² + (0-5)² = (x-2)² + (0+3)²
=> x² + 4x + 4 + 25 = x² - 4x + 4 + 9
=> 8x = 9 - 25 = -16
=> x = -2
So the point is ( -2, 0 ).
