The option that represents the first step is x² + 4x = -3
<h3>How to determine the first step?</h3>
The equation is given as:
x² + 4x + 3 = 0
The first step is to isolate the constant.
So, we have:
x² + 4x = -3
Hence, the option that represents the first step is x² + 4x = -3

Step-by-step explanation:
Answer: 6/40 = 3/20
Step-by-step explanation:
The experimental probability is the number of times the desired result was obtained over the number of times the experiment was carried out:
P= Time the event occurs/ Total number of trials
In this case the event we are looking for is rolling a 3 on the number cube. The total number of trials is: 40
because the student rolls the cube 40 times. and the time that he got the number 3 (the times the desired event occurs) is: 6
because he rolls a 3 on the number cube 6 times. Thus our experimental probability to roll a 3 is: P = 6/40
