16x can be broken down into factors of -105.
21 and -5 come to mind.

7x² + 21x - 5x - 15
7x(x + 3) - 5(x + 3)
(7x - 5)(x + 3) is the factorised form.

Answer:

A. 0.92t

F. t-0.08t

Really easy points!!!!!! Please solve for all three answers.
katen-ka-za [31]

Answer:

1/64, 1/256, 1/1024

Step-by-step explanation:

To get from 16 to 4 we multiply by 1/4

To get from 4 to 1 we multiply by 1/4

Each time we multiply by 1/4

The next term would be 1/16 * 1/4

1/16 * 1/4 = 1/64

The take that term 1/64 and multiply by 1/4

1/64*1/4 = 1/256

Finally take 1/256 and multiply by 1/4

1/256*1/4 =1/1024
