Answer:

Step-by-step explanation:

Hello,

$8a(3x-2y)^2-12x +8y\\\\ = 8a(3x-2y)^2-4(3x-2y)\\\\ = (3x-2y)(8a(3x-2y)-4)\\\\=(3x-2)(24ax-16ay-4)$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

What is the graph of the inequality 3x+2y>-5

Doss [256]

Answer:

The graph with solution is shown below.

Step-by-step explanation:

We need to find the $x-intercept$ and $y-intercept$ for given equation.

For $x-intercept$ , substitute $y=0$

Considering inequality sign as equality and simplifying,

$3x+2y=-5\\3x+0=-5\\x=-\frac{5}{3}$ , point is $(-\frac{5}{3} ,0)$

Similarly,

For $y-intercept$ , substitute $x=0$

We get,

$3x+2y=-5\\0+2y=-5\\y=-5/2$ , point is $(0,-\frac{5}{2})$

We locate this two points on the graph now and join them.

The joining line will be dotted as the inequality has just 'greater than' symbol. The region above the dotted line is the solution to graph.

The diameter of Mercury is approximately 4.9×103 kilometers. The diameter of Earth is approximately 1.3×104 kilometers. About ho

-Dominant- [34]

Hi there!

To get the answer to this question, let's divide the diameter of the Earth by the diameter of Mercury.

$\frac{1.3*10^4}{4.9*10^3}$

We can change this to

$\frac{1.3}{4.9}*\frac{10^4}{10^3}$

Let's solve for each individual fraction

$\frac{1.3}{4.9}$ ≈ 0.27

$\frac{10^4}{10^3}$ = 10

Now, multiply.

0.27 * 10 = 2.7

That's your answer.

Have an awesome day/night! :)
