For this case we have the following polynomial:

We make the following change of variables:

Rewriting we have

Factoring the second order polynomial we have:

Then, returning the change we have:

Finally, we factor the expression in the parentheses of the second term:

Answer:
the completely factored form is:

The shaded area is 299.59un^2.
Y = kx
72 = k*3
73/3 = k
24 = k
y = 24x
Answer: The correct option is the third one; y=10(0.13)^x
Hi there!

Begin by evaluating f - g:
4n - 5 - (n² - 5)
Simplify:
4n - 5 - n² + 5 = 4n - n²
Or it can be written as -n² + 4n to match the first answer choice.
