I’m not quite sure what the question is but i’m guessing you need to simplify, if not lemme know and i’ll try help.

first combine the squared terms which is 1.5z^2+z^2= 2.5z^2

second combine the z terms
6z-3z=3z

then combine the numerical terms
4.5-0.3=4.2

so simplified that equation is
2.5z^2 + 3z + 4.2

Find the GCF of 18xy and 32xyz
Tanzania [10]
<h3>Answer:</h3>

2xy

<h3>Step-by-step explanation:</h3>

GCF stands for the greatest common factor.

Finding All Factors

To find the GCF you need to find the factors of each term. First, find the factors of the coefficients.

  • The factors of 18 include: 1, 2, 3, 6, 9 and 18
  • The factors of 32 include: 1, 2, 4, 8, 16, and 32

Next, lay out the variables that are factors.

  • The variables of 18xy are x and y.
  • The variables of 32xyz are x, y, and z.

Remember that variables count as factors

Greatest Common Factor

Now that we have all of the factors we can find the GCF. The GCF will be the largest number and the most variables that are a factor of both terms.

In this case, the largest factor of 18 and 32 is 2. Since both x and y are factors of both terms, the GCF is 2xy.

The diagram shows the ages and the secondhand prices of 10 cars
EleoNora [17]

From the graph, the coordinates of the cross that represent this car on the graph are ( 8, 2100).

<h3>What is the correlation coefficient?</h3>

The correlation coefficient is a measure of how similar two datasets are acting.

When the correlation coefficient comes out as -1, it means that both the datasets are negatively oppositely correlated.

One data increases and other data starts to decrease in the opposite direction.

When the correlation coefficient comes out below 0, values are negatively correlated.

The correlation shown by the graph is negative.

From the graph, the coordinates of the cross that represent this car on the graph are ( 8, 2100).
