Answer:
f(15) is the area of the rectangular garden for a width of 15 ft
Step-by-step explanation:
we know that
where
x----> is the width of the rectangular garden
(2x+5) ----> is the length of the rectangular garden
so
f(15) -----> is the value of f(x) for x=15 ft
That means
f(15) is the area of the rectangular garden for a width of 15 ft
substitute the value of x and solve
Answer:
x = -3
Step-by-step explanation:
You have the following equation:
you first you distribution property in order to eliminate the parenthesis:
next, you subtract 12 in both sides of the equation:
Finally, you divide the equation by 6 and simplify:
hence, the solution to the equation is x = -3
Answer:
60,480 is the correct answer.
Step-by-step explanation:
First of all, let us have a look at the <em>formula of factorial of a number 'n'</em>:
i.e. multiply n with (n-1) then by (n-2) upto 1.
<em>Keep on subtracting 1 from the number and keep on multiplying until we reach to 1.</em>
<em></em>
So, can be written as:
Similarly can be written as:
Re-writing :
Now, the expression to be evaluated:
