Willing to help but need more information to provide an answer.
Answer:
x = - 3 ± 3![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
Step-by-step explanation:
given the equation x² + 6x - 9 = 0
We can solve for x using the quadratic formula
x = ( - b ±
) / 2a
with a = 1, b = 6 and c = - 9
x = ( - 6 ±
) / 2
= ( - 6 ±
) / 2
= ( - 6 ±
) / 2
= ( - 6 ± 6
) / 2
x = - 3 ± 3![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
Part÷Whole=Percent÷100
Part=X
Whole=55
Percent=222
X÷55=222÷100. Set this up in fraction form, cross-multiply and you will get 100x=222×55
222×55=12,210
100x=12,210: Divide by 100.
X=Part=122.1
What's the models and the situations? Not sure if there's a pic but it's not visible.
The C is a 4. Hope this helped!
