What is true about the solution above.
Masja [62]

ANSWER

x =  \pm \sqrt{3}

and they are actual solutions.

EXPLANATION

The given equation is:

\frac{ {x}^{2} }{2x - 6}  =  \frac{9}{6x - 18}

Cross multiply

{x}^{2} (6x - 18) = 9(2x -6 )

This implies;

{x}^{2} (6x - 18) - 9(2x - 6) = 0

3{x}^{2} (2x - 6) - 9(2x - 6) = 0

Factor

(3 {x}^{2}  - 9)(2x - 6) = 0

3 {x}^{2}  - 9 = 0 \: or \: 2x - 6= 0

3 {x}^{2}   = 9 \: or \: 2x  = 6

{x}^{2}   = 3\: or \: x  = 3

{x}  =  \pm \sqrt{3} \: or \: x  = 3

The domain of the given equation is

x \ne3

Therefore the actual solutions are

x =  \pm \sqrt{3}

NB: x=3 is not in the domain of the given equation. It cannot be an extraneous solution.

What is a number sequence<br>​
disa [49]

Answer:

A number sequence is a list of numbers that are linked by a rule. If you work out the rule, you can work out the next numbers in the sequence. In this example, the difference between each number is 6. So the rule for this sequence is to add 6 each time. So now you can work it out the next number. 27 + 6 = 33.

In the figure below, AB=AE, AC=AD and AP is perpendicular to BE. Prove that BC=DE.
NISA [10]

Step-by-step explanation:

1) In the figure, as AB is equal to AE, ABE is an equilateral triangle.

As AP is perpendicular to BE

=> AP is the height of the triangle ABE.

In an equilateral triangle, the median and the height is the same, so that AP is also the median of the triangle.

=> P is the midpoint of BE

=> PE = PB

2) In the figure, as AC = AD, so that ACD is an equilateral triangle.

As AP is perpendicular to BE,  so that it is perpendicular to CD as well

=> AP is the height of the triangle ACD

In an equilateral triangle, the median and the height is the same, so that AP is also the median of the triangle ACD.

=> P is the midpoint of CD

=> PC = PD

We have:

+) PB = PE

+) PC = PD

=> PB - PC = PE - PD => BC = DE
