The atomic number is defined by the number of protons in an element. An element is defined by the number of protons the nucleus contains and doesn't have anything to do with how many isotopes the element has. Carbon always has an atomic number of 6 and uranium always has an atomic number of 92. I GOTCHU BROOOO GET THATS A BUDDY

Which are steps that could be used to solve 0 = 9(x2 6x) – 18 by completing the square? Check all that apply. 18 81 = 9(x2 6x 9)
Marina CMI [18]

Answer:

18 + 81 = 9(x² + 6x + 9) 11 = (x + 3)²

Explanation:

because  This is the value that completes the square. However, since the entire square is multiplied by 9, this value must be multiplied by 9 before we can add it across the equals:

18 + 9 (9) = 9 (x² + 6x + 9)

18 + 81 = 9 (x² + 6x + 9)

99 = 9 (x² + 6x + 9)

Dividing both sides by 9, we have:

11 = x² + 6x + 9

11 = (x + 3) ²
