In general the binomial expansion is

So in our case, because we want ascending powers of x we'll write,

We need to calculate the binomial coefficients:






Multiply each term in the equation by 4/1.
9-2y+2y+4=24
Combine like terms
13=24
Because the result is false, it is no solution.
A sports field is 200 feet long.
<span>Thus, we have: </span>
<span>L = 200x, where L is the length of x sport fields.</span>
Answer:Convenience sampling
Step-by-step explanation:
This type of sample refers to convenience sampling or grab sampling or accidental sampling.
Convenience sampling is a non-probability type sampling that includes the population which is nearby or available in your zone.
This type of sampling is handy when you need to know about a particular data in less time .Although the result may be somewhat biased because of a certain type of population may exist close to you.This method is most useful for Pilot testing.
first step to remove brackets
here write them in serial order,
=5x²+3x+4+5x²+5x-1
=5x²+5x²+3x+5x+4-1
=10x²+8x-3
