Answer:

Option C : 7 +(-6) + (2+5)x

Step-by-step explanation:

Given :7 + 2(x – 3) + 5x

To Find :Which of the steps has an incorrect justification?

Solution :

7 + 2(x -3) + 5x

7 + 2x -6+ 5x

7-6+2x+ 5x

1+7x

So, Option C has an incorrect justification: 7 +(-6) + (2+5)x

Like terms can be added easily there is no need to apply distributive property .

Hence Option C has an incorrect justification

Nadya [2.5K]

There are several algebraic properties of equality.

<em>The property that shows that both distance are the equal is the symmetric property of equality</em>

Represent the distance between the elephants and the giraffes with x

Represent the distance between the tigers and the zebras with y

The symmetric property of equality states that:

<em>For 2 expressions or numbers; x and y</em>

<em>If x = y, then y = x</em>

<em />

<em />

<em />

In this context, the above property means that:

<em>If the distance between the elephants and the giraffes is the same as the distance between the tigers and the zebras, then both distance are equal</em>

<em />

Hence, the property to use is the symmetric property of equality

Here n = 5, thus

sum = 180° × 3 = 540°
