Choose the expression that represents a cubic expression.
Anna007 [38]

Answer:

10x³ - 6x² - 9x + 12 is a cubic expression ⇒ 2nd

6x + 6 is a linear expression ⇒ 1st

5x² + 9x - 1 is a quadratic expression ⇒ 2nd

Quadratic expression ⇒ 1st

Step-by-step explanation:

* Lets explain the degree of any expression

- The degree of any expression is the greatest power of the variable

- Ex:

# 3x - 3 is a first degree expression

# x² - 3x + 2  is a second degree expression

# 5x³ - 2x² + 5x - 2 is a third degree expression

- The first degree expression is called linear expression

- The second degree expression is called quadratic expression

- The third degree expression is called cubic expression

* Lets solve the problem

∵ The cubic expression is the expression with greatest power of 3

∴ 10x³ - 6x² - 9x + 12 is the cubic expression

∵ The linear expression is the expression with greatest power of 1

∴ 6x + 6 is a linear expression

∵ The quadratic expression is the expression with greatest power of 2

∴ 5x² + 9x - 1 is a quadratic expression

∵ The expression is -2x² + 11

∵ The greatest power of x is 2

∴ -2x² + 11 is a quadratic expression

Can you guys see if you can solve B) for me plz
yanalaym [24]
In the b section on this piece of paper, we can see, that this would practically be a pie graph, or if you would want to call it a graph in general. As the question stated, we see how we would want to find the perimeter of the figure. So this, sense this would only be 1/4 of the figure, we would then do 4(in) x's 4 and from this, your perimeter would give you 16(in).

the ratio of rock music total cds that ella owns is 25/40 .paolo has 59 rock music cds.the ratio of rock music to total cds in h
const2013 [10]
So, the given information tells us that the ratios between ella's rock music to total cds and paolo's rock music to total cds is the same.  This means that we can set them up in a proportion equal to each other. (Let x represent the amount of total cds in paolo's collection)

25/40=59/x

Next, to simplify this equation, we need to use cross-products to cancel out the fraction bars.

25   59
     =
40    x

If done correctly, the resulting equation is 20*x=59*40

When simplified, the resulting equation is 20x=2360

Finally, we need to divide both sides by 20, in order to find out what integer represents x in this equation.

x=118

This means that Paolo has a total of 118 cds in his collection.
 
The question asks how many CDs Paolo and Ella own together.  To figure this out, all you need to do is add how many CDs Ella has (40) to how many CDs Paolo has (118).

40+118=158.

Paolo and Ella's combined collection of total CDs is 158 CDS.
