All real numbers

distribute (x+6)(x+3) to get x^2+6x+3x+18

your equation now looks like this:

x^2+6x+3x+18= x^2+6x+3x+18

because the equations are equal, the answer is all real numbers

Answer:

Step-by-step explanation:

When you roll dice, there are 6 possible outcomes.  

In order to not roll a 6, you'd have to roll either 1,2,3,4,5.

So you have a 5:6 chance of not rolling a 6.

But they're asking you to use the chart.

Based on the chart, you've rolled the die 24+10+8+3+30+15=90 times.

Of those 90 times, you rolled a 6 15 times.

Which means you did not roll a 6 90-15=75 times.

Therefore the probability of not rolling a 6, based on the chart, is 75/90=83%.

Notice that 5/6=83% as well.  So this chart is fairly accurate.

Now for number 2.

Based on the chart, odd numbers appear 24+8+30=52 times out of the 90.

So we can say that odd numbers show up 52/90=58% of the time.

If James is rolling the cube 250 times, we know odd numbers will show up 58% of the time so, .58*250=144 is how many times we can expect to see an odd number appear.
