I believe it’s g(k)=(-k- 3)(-k+3)
So, if the <span>number is between -3 and 3, It couldn't be more than 3, so C isn't the answer. It also doesn't have to be equal to 3.
B, </span><span>|x| < 3, would be your answer.
Hope this helps!</span>
Answer:
x=9/2
Step-by-step explanation:
First distribute 2
2x-4-5=3-2x+6
Add the like terms on the left side -4-5=-9
2x-9=3-2x+6
Do this with the right side 3+6=9
2x-9=-2x+9
Add 9 from the left side to the right side
2x=-2x+18
Then add 2x from the right side to the left side
4x=18
Divide 4 from both sides
x=18/4 or 9/2

x=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}
x=2a−b±b2−4ac
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.
