Answer:
7, -1
Step-by-step explanation:
x^2 - 6x + 7 = 0
(x - 7)(x + 1) = 0
==> x = 7, x = -1
It depends on the given information.
McKenzie's work is correct if the two short sides are given as 5 and 13.
Cara's work is correct is almost correct if 5 is one leg, and 13 is the hypotenuse. The exact answer is 12, but she wrote it as approximately equal. That's her only problem.
By the way, Ddssaa122: when posting questions, the power of a number is written as 5^2 and not 52. If you copy and paste, please make sure you add the caret sign to indicate a power, or else you will suffer by getting a wrong answer. 5^2=5*5, 52=4*13, so they are not the same.
Answer:
240

We have to take out the greatest common factor from the given polynomial to factorize the expression. If you observe the terms of the polynomial, the greatest factor that is common to all the terms is
![4 x^{4}](https://tex.z-dn.net/?f=4%20x%5E%7B4%7D%20)
. So taking it out as common, the factorization of the polynomial will be:
![16 x^{9} -36 x^{5}-8 x^{4} \\ \\ =4 x^{4}(4 x^{5}-9x-2)](https://tex.z-dn.net/?f=16%20x%5E%7B9%7D%20-36%20x%5E%7B5%7D-8%20x%5E%7B4%7D%20%20%5C%5C%20%20%5C%5C%20%0A%3D4%20x%5E%7B4%7D%284%20x%5E%7B5%7D-9x-2%29%20%20%20)
So the option C gives the correct answer
