What are the potential solutions of In(x2 - 25) = 0?
Ox= 113
O x= 15
x=+26
Ox=+10
Answer:
e^0=x^2-25=1
x^2=26
x=sqrt(26), pos and neg
The potential solution of the given equation is x=±√26. Therefore, option C is the correct answer.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
The given equation is ln(x²-25)=0
x²-25>0
(x+5)(x-5)>0 (∵a²-b²=(a+b)(a-b))
x>-5 and x>5
Now, e⁰=x²-25
1=x²-25
x²=26
x=±√26
Therefore, option C is the correct answer.

K is between J and M. L is
between K and M. M is
between K and N. If JN = 14, KM = 4, and JK = KL = LM, what is NL?
(do step-by-step fully pls)
Step-by-step explanation:
given,
K is between J and M, L is between K and M, M is between K and N. JN = 14, KM=4 and JK= KL= LM
NL=?
according to the question,
J-------K-------L------M--------N
We know,
KM= 4
KL+LM=4
KL+KL=4 (LM=KM)
2KL=4
KL=2
SO,
JK=KL=2 and LM=KL=2
we have ,
JN=14
JK+KM+MN= 14
2+4+MN=14
MN=8
Now,
NL=LM+MN= 2+8= 10

Evaluate each expression for the given values of m and n. 2m - 4n(3m – 4) if m= 1 and n= -3 (2)
Answer: -22
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given information
m = 1
n = -3 (2) = -6
Given expression
2m - 4n (3m - 4)
Substitute values into the expression
=2(1) - 4(-6) (3(1) - 4)
Simplify by multiplication
=2 + 24 (3 - 4)
Simplify values in the parentheses
=2 + 24 (-1)
Simplify by multiplication
=2 - 24
Simplify by subtraction

Determine if v 49 is rational or irrational and give a reason for your answer.
The number 49 is rational
because
Step-by-step explanation:
If a number is rational, we can represent it as a fraction.
[tex] \frac{a}{b} [/tex]
Where a and b are intergers.
First, we know that
[tex] \sqrt{49} = 7[/tex]
We can represent 7 as
[tex] \frac{7}{1} ..... \frac{14}{2} .... \frac{21}{3} ..... \frac{n}{y} = 7[/tex]
Where n and y are two numbers that when divided equal 7.
So

Find three consecutive even integers such that five times the second is six more than twice the sum
of the first and third integers
Answer:
The first number = 4The second number = 6The third number = 8Step-by-step explanation:
Let all unknown numbers be represented by the variable x.So;x = first number
x + 2 = second number
x + 4 = third number
placing in a form as demanded by the question.5(x + 2) = 6 + 2x + 2 ( x + 4)
5x + 10 = 6 + 2x + 2x +8
5x - 4x = 14 - 10
x = 4
Therefore;The first number (x) = 4
The second number ( x + 2) = 4 + 2 = 6
The third number (x + 4) = 4 + 4 = 8
Answer:
2x + 2x +2 + 2x +4 = 6x +6 =Sum
5 * (2x +2) = 2 * (2x + 2x +4) +6
10x + 10 = 8x + 8 + 6
2x = 4
x = 2
So the numbers are:
2x or 4
2 x + 2 = 6
2x + 4 = 8
Double-Check
5 * 2nd integer = 30
2 * (1st + 3rd integers) = 24
30 is 6 more than 24

If A/B and C/D
are rational expressions, then
AxC/BxD = AxD/BxC
A. True
B. False
Answer:
True
Step-by-step explanation:
If A/B and C/D are rational expression then
A/B*C/D
Or
A/B*C/D=A/C*B/D
It means that if A/B and C/D are rational expression then their product with each other will also be a rational expression.
