Identify the property that justifies each step asked about in the answer area below. Line 1: \text{Line 1: }\phantom{=}Line 1: =

kipiarov [429]

Answer:

1. Commutative Property of Addition

2. Distributive property

Step-by-step explanation:

Given

$Line 1: 4(8+9x)$

$Line 2: 4(9x+8)$

$Line 3: 36x+32$

Required

Justify each step

From Line 1 to 2:

The property from Line 1 to 2 depicts $a + b = b + a$ ;

i.e.

$4(8 + 9x) = 4(9x + 8)$

This is referred to as Commutative Property of Addition

From Line 2 to 3:

The property here depicts $a(b + c) = a * b + b * c$

i.e.

$4(9x + 8) = 4 * 9x + 4 * 8$

$4(9x + 8) = 36x + 32$

This is referred to as Distributive property

How to solve this step by step

Paha777 [63]

Yo has to factor since we assume that
if you have xy=0, x and y=0

7n^2-48n+36=0
trial and error
(7n-6)(n-6)=0

set each to zero
7n-6=0
add 6
7n=6
divide 7
n=6/7

n-6=0
add 6
n=6

n=6/7 or 6

Dovator [93]

14.7x + 4x = 0*(49y+39y) y = 14

18.7x = 0(686 + 546)

18.7x = 0

x = 0
