Which property is not used to simplify the following expression?
2. (x + 5) + 7x = (2x + 10 + 7x
= (10 + 2x) + 7 x
= 10 + (2x + 7x)
= 10 + 9x
9x +
associative property of addition
commutative property of addition
commutative property of multiplication
distributive property

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

what i would say the best answer is a. 40.5

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 ! ~
