z > -9
Solution Set: (-9, ∞)
1. You have the following quadratic equation and to solve it, you must follow the steps below:
<span>
x</span>²<span>+3=9x
2. The form of the equation that you need to apply the quadratic formula, is:
ax</span>²+bx+c=0
<span>
3. Then:
</span>
x²<span>+3=9x
</span> x²-9x<span>+3=0
</span><span>
4. The quadratic formula is shown below:
x=(-b±√(b^2-4ac))/2a
5. Then, you have:
a=1
b=-9
c=3
6. When you substitute the values into the quadratic formula, you obtain:
x1=0.34
x2=8.65</span>

Answer:
11
Step-by-step explanation:
11 + 8 + 14 + v + 8 + 14
================== = 11 Combine Terms
6
(55 + v) / 6 = 11 Multiply by 6
55 + v = 11 * 6 Combine the right
55 + v = 66 Subtract 55
55-55+v = 66- 55
v = 11
