Answer:
16
Step-by-step explanation:
24 minus 8.
The reason I subtract 8 from 24 is because the eight is a <u><em>negative</em></u>. Also, you can do it the opposite way like -8 ADD 24 on so you'll end up with 16 but it's a longer process.
Answer:
BD = 8 cm
Step-by-step explanation:
Point O divides the diagonals proportionally, so ...
... AO/AC = BO/BD = 3/4
Then ...
... BO = BD·3/4 . . . . . multiply by BD
... BD = 4/3·BO = 4/3·(6 cm) . . . . . multiply by 4/3; substitute the value of BO
... BD = 8 cm
