Answer:

46%

Step-by-step explanation:

<u>Step 1: Make an expression</u>

<u /> $39.00 * x = 56.94$

$39x = 56.94$

<u /> $1.46 - 1$ -> Gives us the increased percent

$0.46 * 100$

What is the most logical first step in solving the equation x2+6x+9=10?

valentina_108 [34]

You need to make the right side = 0
To do this you subtract 10 from both sides of the equation:-

x^2 + 6x + 9 - 10 = 10 - 10
x^2 + 6x - 1 = 0
