Answer is 12/15 x 5/9 = 4/9

Step by step: first cross cancel to make your numbers to multiply smaller.
I divided 12 and 9 by 3 and 5 and 15 by 5, see attachment.

Then I multiplied across

Answer is 4/9

Solve 3x^2 + 6x+15=0

Elden [556K]

Answer:

The solution of given equation is ( - 1 + 2 i ) , ( - 1 - 2 i )

Step-by-step explanation:

Given equation as :

3 x² + 6 x +15 = 0

The value of x fro the quadratic equation a x² + b x + c = 0 is obtained as

x = $\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}$

So , from given eq , the value of x is now obtain as

x = $\frac{-b\pm \sqrt{b^{2}-4\times a\times c}}{2\times a}$

Or, x = $\frac{-6\pm \sqrt{6^{2}-4\times 3\times 15}}{2\times 3}$

Or, x = $\frac{\sqrt{-144} }{6}$

∴ x = ( - 1 + 2 i ) , ( - 1 - 2 i )

Hence The solution of given equation is ( - 1 + 2 i ) , ( - 1 - 2 i ) Answer

If x. 5x and 6x are the measures of the

max2010maxim [7]

Answer:

<em>Since one of the angles is 90°, the triangle is right.</em>

Step-by-step explanation:

<u>Angles in a Triangle</u>

The sum of angles in a triangle is 180°. We are given the angles are x, 5x, and 6x, thus:

x + 5x + 6x = 180

Simplifying:

12x = 180

Dividing by 12:

x = 180/12 = 15

x = 15°

5x = 75°

6x = 90°

Since one of the angles is 90°, the triangle is right.

Identify the horizontal

jonny [76]

Answer:

y=0

Step-by-step explanation:

Hello!

To solve this problem and find the asymptote you must find the value of x, for which F (x) (or y) becomes infinite, for this we solve the equation for X

$y=\frac{3}{5X} \\X=\frac{3}{5y}$

As you can see if Y takes a value of zero, then X would tend to be an infinitely large value so we conclude the horizontal asymptote is y = 0, I also attached the graph!
