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

a. 19,958,400

step-by-step explanation:

hope this

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
