If we let y be equal to zero, we get the roots of the equation. Because the equation is already in the factored form, we then say that the roots of the equation are x = 3 and x = 5. Another thing that is notable of this equation is that the graph would pass the x-axis at the points 3 and 5.
This is a quadratic equation because there are two roots and the highest exponent achievable by performing the expansion of the terms is 2. this equation can be of a parabola and the opening is upward because of the positive value of the numerical coefficients both of y and x in the opposite sides of the equation.
The answer is 2.25g/ml or 2.25 g/cm³
To do this, you need to know the formula of density. Density is the mass per unit of volume.

Where:
D = Density
M = Mass
V = Volume
You already have your mass, which is 45.0g, so what is your volume?
A graduated cylinder measures the volume of liquids. The procedure that was done here is called the displacement method. You can get an estimated volume of an irregular object by subtracting the initial volume from the final volume.
In this case, it would be:
<span>70.0mL - 50.0mL = 20.0 mL
</span>The volume is then 20.0mL.
Now that we have the volume we can solve for density.


Now take note that 1mL = 1cm³. So you can also express the answer as
2.25g/cm³.
The length of AB wit the coordinate (-6, 5) and (8,5). is 14 units
<h3>Distance between two points</h3>
A rectangle is a quadrilateral with 4 sides and angles
Taking the length of AB.
Since AB is slant line, the length of AB will be determined using the distance formula as shown;
D = √(-6-8)² +(5-5)
D = √(-14)²
D = AB = 14 units
Hence the length of AB wit the coordinate (-6, 5) and (8,5). is 14 units

By the Pythagorean theorem:
с = √(3² + 6²)
= √(9 + 36)
