Answer:
This equation has no real roots
Step-by-step explanation:
We want to solve

We group all terms on the left:


Divide through by -6

The discriminant is

This means the given equation has no real solution, since the discriminant is less than 0

1/3
Step-by-step explanation:
The volume of a pyramid is always 1/3 of a prism and the volume of a prism is 3 times the volume of the pyramid
Answer: -3.4.(-2) • (-2)= -48
Step-by-step explanation: please keep in mind that every number that you multiply by 0 is equal to 0, it does not mind if number is positive or negative the result will be always 0, if we have this clear we can pass with following step.
then you do not need resolve the equation with 0 because you know that result will be 0, after that we get only one equation the first one.
-3 * 4 * (-2) * (-2)
keep in mind when you are multiplying numbers with the same sign the product will be positive, but when you are multiplying numbers with different signs the result will be negative.
we can resolve this value by value for example
-3 * 4 * (-2) * (-2)
-3 * 4= -12
then we get the following equation
-12 * (-2) * (-2)
then we can pass with the next value
-12 * (-2) = 24
then we get the following equation
24 * (-2) = -48
as you can see this will be the only one equation with a negative product.
The answer is A because the sign changes
