Answer: $D=96$

Step-by-step explanation:

You must add 2 to both sides of the equation:

$3x^2-10+2=-2+2\\3x^2-8=0$

You can find the discriminant of the quadratic equation given in the problem with the formula shown below:

$D=b^2-4ac$

Based on the given equation, you have that:

$a=3\\b=0\\c=-8$

Susbstitute values. Then you obtain:

$D=0^2-4(3)(-8)=96$

11. The table shows the lengths of fish caught by three,

blsea [12.9K]

Numbers can be ordered in ascending or descending order.

The length of fishes from greatest to least is

$Emily = 12 \frac 34$ .
$Emma = 12.7$ .
$Anne = 12 \frac 35$

Given

$Emma = 12.7$

$Anne = 12 \frac 35$

$Emily = 12 \frac 34$

Convert all fractions to decimals

$Emma = 12.7$

$Anne = 12.6$

$Emily = 12.75$

Arrange from greatest to least

$Emily = 12.75$

$Emma = 12.7$

$Anne = 12.6$

<em>Hence, the length of fishes from greatest to least is </em>

$Emily = 12 \frac 34$ $Emma = 12.7$ $Anne = 12 \frac 35$
