jayden used the following steps to simplify the given expression.

-3 + 2(2 + x + 3)

step 1: = -3 + 2(x + 2 + 3)
step 2: = -3 + 2(x + 5)
step 3: = -3 + 2x + 10
step 4: = 2x + (-3) + 10
step 5: = 2x + 7

what property of real numbers was used in step 3?
a)distributive property
b)associative property of addition
c)commutative property of addition
d)associative property of multiplication

Option A -distributive property

Step-by-step explanation:

Given : expression     -3 + 2(2 + x + 3)

Step 1: = -3 + 2(x + 2 + 3)

Step 2: = -3 + 2(x + 5)

Step 3: = -3 + 2x + 10

Step 4: = 2x + (-3) + 10

Step 5: = 2x + 7

In step 3 distributive property is applied i.e. c(a+b)=ca+cb

in step 2- 2(x+5) when we apply distributive property it became

2x+10

Therefore, option A is correct

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
