Answer:

The coefficients are simply 12, 2, 4, and 7.

Step-by-step explanation:

Coefficients are the numbers that come before terms. Each term has a coefficient before it.

Answer:

The coefficients in the expression are: 12, 2,4 and 7

Step-by-step explanation:

Expressions like this 12xy^{3} +2x^{5}y+4x^{5}x^{2}+7x^{5}y are known as polynomials in two variables.

In a general form a polynomial in two variables is an expression that can be written in the form:

P(x,y) = a_{0,0}+a_{1,0}x+a_{0,1}y+a_{2,0}x^{2}+a_{1,1}xy+a_{0,2}y^{2}+...+a_{n,0}x^{n}+...+a_{0,n}y^{n}, where a_{0,0} or a_{n,0} are called the coefficients.

To get polynomial coefficients, you can take the numbers in front of each terms, for example 12xy^{3} is known as term and the coefficient is 12.

Or compare the general form of a polynomial with the polynomial 12xy^{3} +2x^{5}y+4x^{5}x^{2}+7x^{5}y and you find that the coefficients in the expression are: 12, 2,4 and 7

Determine the volume of the rectangular prism.<br>​
Flauer [41]

Answer:

<h2><u>50 ft³</u></h2>

Step-by-step explanation:

We know the formula for a rectangular prism is length × width × height

We also know all the sides so we can rewrite the formula replacing variables.

The length is 8, the width is 2\frac{1}{2} and the height is 2\frac{1}{2}

8 × 2\frac{1}{2} × 2\frac{1}{2}

Multiply which ever way is easy for you. I am just multiplying from left to right.

8 × 2\frac{1}{2} = 20

20 × 2\frac{1}{2} = 50

Now we get 50. Before we put our answer as 50, there are two more steps.

First we need to add the measurement unit which is feet or ft

We also need to add ³ since it is volume

<u>50 ft³ is our final answer</u>

How do I solve this question?
Montano1993 [528]

Answer:

p = \frac{3}{2} , q = 9

Step-by-step explanation:

4x² + 12x ( factor out 4 from each term )

= 4(x² + 3x)

Using the method of completing the square

add/subtract ( half the coefficient of the x- term)² to x² + 3x

= 4(x² + 2(\frac{3}{2} )x + \frac{9}{4} - \frac{9}{4} )

= 4(x + \frac{3}{2} )² - 4 × \frac{9}{4}

= 4(x + \frac{3}{2} )² - 9
