Answer:
Step-by-step explanation:
7) R(3 , -9) ; S ( -4,5) ,T (-8,13)
RS = √(x₂ - x₁)² + (y₂ - y₁)²
= √(-4 -3)² + ( 5 - [-9] )² = √(-4 -3)² + ( 5 + 9 )²
= √(-7)² + ( 14)² =√ 49 + 196= √ 245
ST = √( -8 - [-4] )²+ (13 - 5)² + = √(-8 + 4)² + ( 13 - 5 )²
= √(-4)² + ( 8)² =√ 16 + 64= √ 80
RS ≠ ST
8) S is not the midpoint of RT.
9) AB = 14
AB + BC = AC
14 + 3X - 4 = 4X + 4
4X - 3X = 14 - 4 - 4
X = 6
AC = 4x + 4 = 4*6 + 4 = 24 + 4 = 28
BC = 3x - 4 = 3*6 - 4 = 18 -4 = 14
10)AB = BC .So B is the midpoint of AC
