Factorise : 64a cube minus 27b cube minus 144a square b plus 108ab square .

Svetlanka [38]

Answer:

$16a(4a^2-9a)+27b^2(4a-b)$

Step-by-step explanation:

The question is not properly formatted, here is a good format for proper understanding and readability

$64a^3-27b^3-144a^2+108ab^2$

let us first collect/ group like terms

$64a^3-144a^2+108ab^2-27b^3$

we can now bring out the common factors we have

$16a(4a^2-9a)+27b^2(4a-b)$

<em>The simplified expression is </em>

$16a(4a^2-9a)+27b^2(4a-b)$

Answer:

The probability that you would choose a green candy: $\frac{45}{139}$ or approximately 32%.

Step-by-step explanation:

The general form of probability can be calculated as the following fraction:

$\frac{number of desired outcomes}{total number of outcomes}$

First, to find the total number of outcomes, you need to add all of the candies together: 42 + 45 + 20 + 32 = 139, so there are 139 total outcomes. Since there are a total of 45 green candies, the probability of choosing green from the total can be written as:

$\frac{45}{139}$

Dividing the numerator by the denominator and multiplying by 100 gives us the percentage of approximately 32%.

A movie theater is located on a map of a city represented by a coordinate plane. The location of the movie theater is at (−4, 2)

Romashka [77]

See the graph

<h2>Explanation:</h2>

Remember to write complete questions in order to get good and exact answers. Here you haven't provided any option, but it's easy to plot this point on a coordinate system in order to know the location of the movie theater. We know that this theater is at the point:

$(-4,2)$

So let's plot this point in the cartesian plane:

The x-coordinate is -4
The y-coordinate is 2.

So the graph is shown below. Remember that the horizontal axis is called the x-axis while the vertical axis is called the y-axis.

x > 0 for the x-values to the right of the origin.

x < 0 for the x-values to the left of the origin.

y > 0 for the y-values above the origin

y < 0 for the y-values below the origin.
