C. (3x+1)(3x-2) 3x times 3x= 9x^2 and 3x times -1= -3x
2 times 3x= 6x and 2 times -1= -2
9x^2- 3x+6x-2
9x^2+3x-2
Hope I explain this more clearly for you.
The graph should look like the below image
It’s a straight line that passes through the origin.
Answer:
L*W*H (Length*Width*Height)
Step-by-step explanation:
Well, volume specifically defined as the amount of space an object takes up, so it can be found using the formula Length x width x height. :D
Answer:
a)
b)
And adding the values we got:
Step-by-step explanation:

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest "number of teens that have heard of a fax machine", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Part a
For this case we want this probability:
Part b
For this case we want this probability:
And adding the values we got:
Cannot be determined because if your only given two thing (FG and the angle measure of F) thats not enough informations. The only way you know if a triangle is similar with only two pieces of information would be for the angle angle postulate.
