Which property can you use to show that 3x + (2x + 4) is equivalent to (3x + 2x) + 4?

Step-by-step explanation:

3x + (2x + 4) is equivalent to (3x + 2x) + 4

because there is no change of signs taking place as there is no (-) sign in front of the brackets

3x + (2x + 4) | (3x + 2x) + 4

3x + 2x + 4 | 3x + 2x +4

5x + 4 | 5x + 4

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
