The answer is:

<h2>
Why?</h2>
To solve the problem, we need to perform the operations and then, add like terms.
We need to apply the distributive property, which is defined by the following way:

Also, we need to remember how to add like terms. Like terms are terms that share the same exponent and the same variable, for example:

We were able to add only the first two terms since they are like terms, both are sharing the same exponent and the same variable.
So, we are given the expression:

Then, solving we have:

Hence, we have that the answer is:

Have a nice day!
Answer:
The probability mass function is expressed as:
P(x) = [(x+r-1)C(r-1)]*[p^r]*[(1-p)^x]
Step-by-step explanation:
This is not a binomial distribution. It is actually a negative binomial distribution. The probability mass function is expressed below:
P(x) = [(x+r-1)C(r-1)]*[p^r]*[(1-p)^x]
where:
x = number of failures
r-1 = number of successes (10 in this scenario)
p = probability of a success
nCr = n!/[r!(n-r)!]
The main formula difference in the positive binomial versus negative binomial is this: With respect to the negative binomial, it is obviously known that the last event will be: when we reach our 10th "head", we stop .
Thus, the last flip will ALWAYS be a "head".
Step-by-step explanation:
according to the question
55x⁶+22x⁴
11x⁴(5x²+2)
so
width:11x⁴
length:5x²+2
