The correct answer is C
3+ 0 is 3
3^2 + 0 is 9
Answer:
4.66 (4 2/3, 14/3)
Step-by-step explanation:
I am pretty sure that it is the first choice because it is the only one that is true
z^2 - z - 72
z^2 - 9z + 8z - 72
<u>Step 1</u>: 72 = 9 * 8 and when we subtract -9+8 = -1 and that's how I went from z^2 - z - 72 to z^2 - 9z + 8z - 72.
<u>Step 2</u>: Taking out common value from first and second; and third and fourth.
z^2 - 9z = z(z - 9)
8z - 72 = 8 (z - 9)
z^2 - 9x + 8x - 72
z(z-9) + 8(z-9)
(z-9) (z+8)
I'm almost positive that the answer is 3.
