the complete question in the attached figure
we have that the area of a square A= s*s
if the side is s inches long
then A= s² in²
therefore
the answer is the option D A=s² sq in
What is the resulting equation when the expression for y in the second equation is substituted into the first equation? 3x y = 1
1 answer:
After putting the value of y from the second equation to the first equation, the resultant equation is .
GIven:
The equations are:
It is required to put the value of y from second equation to the first equation.
<h3>How to solve equations?</h3>The value of y from the second equation is,
Now, put this value of y in the first equation as,
Therefore, after putting the value of y from the second equation to the first equation, the resultant equation is .

Tossing a coin is a binomial experiment.
Now lets say there are 'n' repeated trials to get heads. Each of the trials can result in either a head or a tail.
All of these trials are independent since the result of one trial does not affect the result of the next trial.
Now, for 'n' repeated trials the total number of successes is given by
where 'r' denotes the number of successful results.
In our case and
,
Substituting the values we get,
Therefore, there are 1352078 ways to get heads if a person tosses a coin 23 times.
