What is (4x-2)•6(2x+7) in standard form

1 answer:

4 0

  y = 12(2x - 1)(2x + 7)
  y = 12(2x(2x + 7) - 1(2x + 7))
  y =12(2x(2x) + 2x(7) - 1(2x) - 1(7))
  y = 12(4x² + 14x - 2x - 7)
  y = 12(4x² + 12x - 7)
y = 12(4x²) + 12(12x) - 12(7)
y = 48x² + 144x - 84
-48x² - 144x + y = -84
-1(-48x² - 144x + y) = -1(-84)
-1(-48x²) + 1(144x) - 1(y) = 84
48x² + 144x - y = 84

Select the three ratios that represent the number of red cars to blue cars.

Lorico [155]

Three ratios that represent the number of red cars to blue cars are

2 : 3

6 : 9

8 : 12

$\texttt{ }$

<h3>Further explanation</h3>

<u>Given:</u>

Number of Red Cars = 4

Number of Blue Cars = 6

<u>Asked:</u>

Ratio = ?

<u>Solution:</u>

<em>Number of Red Cars = R</em>

<em>Number of Blue Cars = B</em>

The ratio that represent the number of red cars to blue cars is :

$R : B = 4 : 6$

We can find other ratio by dividing or multiplying the above comparison with the same number :

$R : B = (4/2) : (6/2) = 2 : 3$

$R : B = (4 \times 2) : (6 \times 2) = 8 : 12$

$R : B = (4 \times \frac{3}{2}) : (6 \times \frac{3}{2}) = 6 : 9$

$\texttt{ }$

<h3>Conclusion:</h3>

Three ratios that represent the number of red cars to blue cars are:

2 : 3

6 : 9

8 : 12

The table and the graph below each show a different relationship between the same two variables, x and y:

gavmur [86]

The value of y would be 20 times more valuable than 12 because the pattern for this table is y=20x. Let me know if I'm right :)

Explain the difference between 1/2 and 1/2%

Gnoma [55]

But the correct usage is that 1:2 means a ratio of 1 to 2, meaning 1 part of something and 2 parts of something else (not out of 2 parts total) ...
