The greatest common factor of 64 and 96 is... uhh... hmm... 32! Because 64/32 is 2, and 96/32=3. 2 and 3 have no factors in common, except 1.
The answer is 32(2+3).
This means 32*2 + 32*3
this is the same as 64+96

GH bisects CF. CF = 2y-2 and CD = 3y -11. find CD
love history [14]

Answer:

CD = 4

Step-by-step explanation:

GH bisects CF  <u><em>means</em></u>  CF = 2 CD

CF = 2 CD

⇔ 2y - 2 = 2×(3y - 11)

⇔ 2y - 2 = 6y - 22

⇔ 22 - 2 = 6y - 2y

⇔ 20 = 4y

⇔ y = 5

<u>Calculating CD ,For y = 5</u> :

CD = 3y - 11

     = 3(5) - 11

     = 15 - 11

     = 4
