What is Logarithm?The exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if [tex]b^x[/tex] = n
Given:
logx + log(x + 2) = log(3x)
Using the Property
log a+ log b= log(ab)
So, logx + log(x + 2) = log(3x)
log ( x(x+ 2)) = log( 3x)
Now, Comparing
x(x+2) = 3x
x² + 2x = 3x
x² = x
x²-x= 0
x(x-1)= 0
x=0 or 1.

Alex bought a new aquarium. He is in the process of setting it up. The aquarium is in the shape
of a right rectangular prism and the dimensions, in inches, are 36 7/8 x 19 x 24 5/8. During
the set-up, Alex fills the aquarium with 6,039 in3 of water.
PLEASE HELP
Answer:
39.00%
Step-by-step explanation:
Given
Dimension: 36⅞ by 19 by 24⅝
Volume of Water = 6039in³
Required
What percent of the volume of the aquarium is filled with water?
First, we need to calculate the volume of the aquarium.
This is calculated by multiplying the dimensions of the aquarium
Volume = 36⅞ * 19 * 24⅝
Volume = 295/8 * 19 * 197/8
Volume = 1104185/64
Volume = 17252.89
The percent filled with water is calculated using the following formula:
%Percent = (Volume of water * 100%)/(Volume of aquarium)
%Percent = (6039 * 100%)/(17252.89)
%Percent = (603900%)/(17252.89)
%Percent = 39.00% (approximated)
Hence, the water occupies 39.00% of the aquarium

Una caja contiene bolas blancas, negras y rojas. Si la quinta parte de las bolas son blancas, la séptima parte son
negras y hay 7 bolas rojas, ¿cuántas hay en total?
Responder:
Número total de bolas = 245/23
Explicación paso a paso:
Dado que:
Bolas blancas = 1/5
Bolas negras = 1/7
Bolas rojas = 7
Sea el número total de bolas = x
Bolas blancas = 1 / 5x
Bolas negras = 1 / 7x
Por tanto, total;
(x / 5 + x / 7 + 7) = x
((7x + 5x) / 35) +7 = x
(12x / 35) + 7 = x
7 = x - 12x / 35
7 = (35x - 12x) / 35
7 = 23 veces / 35
245 = 23x
x = 245/23

Use the figure below.
Select all the lines in the proof of △ABC≅△CDA that have the correct justification.
∠ACB≅∠CAD, Alternate Interior Angles Theorem
△ABC≅△CDA, SAS Triangle Congruence Theorem
∠BAC≅∠DCA, Alternate Interior Angles Theorem
AB || CD and BC || AD, ASA Triangle Congruence Theorem
AC≅AC, Reflexive Property of Congruence
Answer:
∠ACB≅∠CAD, Alternate Interior Angles Theorem
∠BAC≅∠DCA, Alternate Interior Angles Theorem
AC≅AC, Reflexive Property of Congruence
By A-S-A congruence, the △ABC≅△CDA.
Step-by-step explanation:
Given the figure:
We are given that:
Side BC || AD
Side AB || DC
Let us have a look at a few properties first.
Alternate Interior Angle Theorem: It states that when two parallel lines are cut by a line then the alternate angles which are on the interior side are equal to each other.
Reflexive Property of Congruence: It states that a side or angle is always congruent to itself.
Now, let us consider the triangles:
△ABC and △CDA.
Side BC || AD
Therefore,
∠ACB≅∠CAD, Alternate Interior Angles Theorem
Side AB || DC
Therefore,
∠BAC≅∠DCA, Alternate Interior Angles Theorem
Also, Side AC is common.
AC≅AC, Reflexive Property of Congruence
Therefore, by A-S-A congruence, the △ABC≅△CDA.

There are 2 Violet balls and four pink balls in a bag if two balls or tomorrow and one after another then what is the possibility of getting a violet first and a think Max is the first ball joints replaced
Answer:
The probability is 2/9
Step-by-step explanation:
Here , we want to find the probability of getting a violet ball first and a pink ball secondly if the violet ball is replaced
probability = number of balls of same color/total number of balls
The total number of balls = (2 + 4) = 6 balls
Probability of selecting a violet = 2/6 = 1/3
Probability of selecting a pink afterwards with replacement = 4/6 = 2/3
So the probability of selecting the balls in that order will be;
1/3 * 2/3 = 2/9

Compare the decimal forms of 2/5 and 4/9
how are they alike and how are they different?
Answer:
These numbers are not the same as 4/9 is bigger than 2/5.
Step-by-step explanation:
As we have to compare the decimal forms of 2/5 and 4/9.
We determine that the numbers in decimal forms are:
[tex]\frac{2}{5}=0.4[/tex]
[tex]\frac{4}{9}=0.44444...\:[/tex]
so
[tex]\frac{4}{9}=0.44444[/tex] is clearly bigger than [tex]\frac{2}{5}=0.4[/tex].
Therefore, these numbers are not the same as 4/9 is bigger than 2/5.
