How do I do this I need help fast

the answer is 7:6 :)

Step-by-step explanation:

scale factor = 1.5

side DE / FD = 9 / x

sides BC / AC = 6 / 7

ratios are the same

therefore side FD = 10.5

side AB = 8

scale factor = 12 / 8 = 1.5 or 3/2

answer: true

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
