Answer:
For step three she could multiply the two parenthesis against each other to get 3(x² - 10x + 25) - 2 + 4x
Step-by-step explanation:
step 1: 3(x - 5)² - 2 + 4x
step 2: 3(x - 5)(x - 5) - 2 + 4x
For step three she could multiply the two parenthesis against each other to get 3(x² - 10x + 25) - 2 + 4x

The correct justification for the first step in solving the provided equation is that the first step should be distributive Property
<h3>What is the property of equality?</h3>
Property of equality says that by performing any mathematical operation, of both sides of a expression does not change the original value of the equation.
The equation given in the problem is,

To solve the above equation, we need to open the brackets of the equation. To do this, we need to use the distributive property of the equality.
This can be done by multiplying the number 3 inside the bracket (x-4). This operation simplify the equation, to solve it further. Therefore,

Hence, the correct justification for the first step in solving the provided equation is that the first step should be distributive Property.

The distances from Boston to New York and New York to Boston stayed the same. Going was 45mph and returning was 65mph. The average would just be the sum of the two, divided by 2
(45+65)/2 = 55mph average
They run parallel to each other when graphed.
