Area = 1/4√(5(5+2√5))a^2. a is the length of a side. If you plug in 10 as a, you get approximately 172, which is about the same as the 1st option .
Hold on, does the equation look like this? (x^2+6)/x-6? Because if so then you'd substitute nine for x first. Then you'd multiply nine by itself getting eighty-one, after that add six to get eighty-seven. substitute nine for x one more and subtract six. take eighty-seven divided by three to get an answer of twenty-nine. But if the equation is saying the square of nine aside from nine squared then you'd have an entirely different problem. That one would look similar to *square symbol*(9)+6/9-6
, You'd solve this by finding the square of nine which is three then you'd add six and get a numerator of nine. Then you go about the bottom the same as you would have in the first equation, subtract six from nine giving you a denominator of three so you now have nine over three which simplified is three.
The two answers are 29 or 3 depending on the equation.
Y= x/ + 600
