Which expression is represented by the model?

4x-3

Step-by-step explanation:

I have never worked with the program you are using, but if i were to assume,

there are four Xs (4x) and three minus signs, (-3)

so 4x-3 make the most sense to me.

i hope this helps!

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 ! ~

answer: #1 ads up by 8 and i don't know #2
