Step-by-step explanation:
multiply it
x²-3x+3x-9=0
x²-9=0
x²=9
square root both side we get
x=3
<h3>I'll teach you how to find the period of f(x)=sin(x)</h3>
-------------------------------------------------------
A period of a sin is is the length of one cycle.
The original period of the sine curve is 2π.
If x is multiplied by a constant that can change the answer of the period.
The period of the basic sine function f(x) = sin(x) is 2π.
Your Answer Is 2π.

Answer:
The last option y<4. Y is less than 4 since the shaded region is below 4 on the y Axis.
Answer:
5x^2 + 4x + 3.
Step-by-step explanation:
While I'm a little confused on what is closed and open parenthesis/brackets, I think I understand what you mean. In (5x^2+3x-2)+(3x-2x+5), the brackets can simply be removed as there is no multiplication between them. This means we get 5x^2 + 3x - 2 + 3x - 2x + 5. Combining like variables, we get 5x^2 + 4x + 3.
