I dont understand this problem

D and F

Step-by-step explanation:

can be rewritten as .

From there you can use the quadratic formula (ignore the A, I can‘t seem to remove it), where a=1, b=4, and c=-8.

Then you get

Then you get

So

Which means or which are choices D and F.

answer: this is not a question

step-by-step explanation: this is a answer

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
