How would you measure the volume of a brick that contains holes

vaieri [72.5K]

In order to measure the volume of a brick that contains holes, what you need to do is to get the volume of both the brick as a whole, and the volume of the holes. Once you have the volume, you subtract the volume of the holes to the volume of the brick. The final answer would be the volume of a brick that contains holes. Hope this helps!

Explain how to use the discriminant to determine the number and type of roots of a quadratic equation.

baherus [9]

The general form of the quadratic equation is :

$ax^2+bx+c=0$

The discriminant is :

$D=b^2-4\cdot a\cdot c$

And the general solution is :

$x=\frac{-b\pm\sqrt[]{D}}{2\cdot a}$

So, there are 3 situations for D

1. D = 0

So, the roots of a quadratic equation are two similar roots

2. D > 0

so, roots of a quadratic equation are two different roots

3. D < 0

so, roots of a quadratic equation are not real, two comlex roots

raketka [301]

The first step to solving this equation is to change the signs on both sides of the equation
y = - $\frac{2}{5}$ x + 3
Since we don't know what x is but we do know why y is,, we will write our answer with the answer to y and x being left as undefined.
y = - $\frac{2}{5}$ x + 3, x ∈ R
Let me know if you have any further questions
