How do you simplify an expression like -3x + 15 - 8x? do you combine like terms and if so, how?​

so, with terms like -3x and -8x remember to keep the negative or positive sign the same when combining like terms.

in this instance the simplified expression would be:

15 - 11x

because -3x - 8x = -11x

does this make sense? lmk if u need help

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 ! ~
