Maxim has been offered positions by two car companies. The first company pays a salary of $8000 plus a commission of $900 for ea

Kaylis [27]

Answer:

16 cars.

Step-by-step explanation:

Let x represent number of sold cars.

We have been that 1st company pays a salary of $8000 plus a commission of $900 for each car sold. We can represent this information in an expression as:

$900x+8000$

We are also told that second company pays a salary of $14400 plus a commission of $500 for each car sold. We can represent this information in an expression as:

$500x+14,400$

To find the number of cars sold, which will make the total pay the same, we will equate both expressions and solve for x as:

$900x+8000=500x+14,400$

$900x-500x+8000=500x-500x+14,400$

$400x+8000-8000=14,400-8000$

$400x=6,400$

$\frac{400x}{400}=\frac{6,400}{400}$

$x=16$

Therefore, 16 cars would need to be sold to make the total pay the same.

Expand, answer should be a polynomial in standard form<br><br> (5a+2)(a+4)=

castortr0y [4]

Answer:

The standard form of the expression (5a+2)(a+4) is $5a^{2} + 22 a + 8$ .

Step-by-step explanation:

Here, the given expression is (5a+2)(a+4).

Now, (5a+2)(a+4) = 5a(a+4) + 2(a+4)

= $5a^{2} + 20 a + 2a + 8$

= $5a^{2} + 22 a + 8$

or, $(5a+2)(a+4) = 5a^{2} + 22 a + 8$

Also, Standard Quadratic form is $ax^{2} + bx + c = 0$

Hence, the standard form of (5a+2)(a+4) is $5a^{2} + 22 a + 8$ .

Clara created the poster shown below:

lana66690 [7]

Answer:

$length=4\ cm\\width=6\ cm$

Step-by-step explanation:

Given the rectangular poster shown in the picture, you know that its dimensions (its width and its lenght) are:

$w_1=24\ cm\\l_1=16\ cm$

In order to calculate the dimensions of the rectangular at $\frac{1}{4}$ times its current size, you need to multiply the original lenght by $\frac{1}{4}$ and multiply the original width by $\frac{1}{4}$ .
