Which property is illustrated by the equation 7(x + 4) = (x+4) · 7?
A. Commutative Property of Addition
B. Commutative Property of Multiplication
C. Distributive Property
D. Associative Property of Addition

B

Step-by-step explanation:

Commutative means that you change the order of an operation. So in this case, the 7 is written on the left of the brackets on the left side of the equation and on the right side of the brackets on the right side of the equation.

You are multiplying not adding. That makes A incorrect.

You have not removed the brackets so the answer is not C.

It's not addition so it's not D.

B

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.

29 mil
