Could anyone help me with this question? Thank you!
Answer:
C
Step-by-step explanation:
We want to simplify the rational expression:
[tex]\displaystyle \frac{n^4-11n^2+30}{n^4-7n^2+10}[/tex]
First, we can factor both the numerator and the denominator. This yields:
[tex]\displaystyle =\frac{(n^2-6)(n^2-5)}{(n^2-2)(n^2-5)}[/tex]
Cancel like terms:
[tex]\displaystyle =\frac{(n^2-6)}{(n^2-2)}[/tex]
However, since we canceled a term from our expression, we must place restrictions in order to stay true to the original expression.
Rational expressions are undefined whenever the denominator equals 0. The denominator is (before canceling):
[tex](n^2-2)(n^2-5)=0[/tex]
Solve for n. By the zero product property:
[tex]n^2-2=0\text{ and } n^2-5=0[/tex]
Therefore:
[tex]n^2=2\text{ and } n^2=5[/tex]
By taking the square root of both sides (since we are taking an even root, it is required to have plus/minus):
[tex]n=\pm\sqrt{2}\text{ and } n=\pm\sqrt5[/tex]
Therefore, our fully simplified expression is:
[tex]\displaystyle \frac{n^2-6}{n^2-2}\, ,n\neq \pm\sqrt5, \pm\sqrt2[/tex]
Hence, our answer is C!
What is the measure of angle DEG on circle O
9514 1404 393
Answer:
50°
Step-by-step explanation:
Angle DEG is also angle DEC. It subtends arc DC as does inscribed angle DFC. Inscribed angles that subtend the same arc have the same measure.
∠DFC = ∠DEG = 50°

In a baseball card collection, 40% of the cards are worth more than 100$. If 12 cards in the collection are worth more than $100, how many total baseball cards are in the collection?
Answer:
30
Step-by-step explanation:
12 is 40% of the total number of cards.
12 = 0.4x, where x is total number of cards
/0.4 /0.4
30 = x
30 cards

I think the question is asking you for fractions smaller than 1/2, but Im not sure. Sorry if this wasnt the answer you were looking for.
Rmember that the bigger the denominator (bottom number), the smaller the fraction.
John can play 12 songs on his guitar but learns 1 new song every week. Aiden can play 4 songs but learns 2 every week
Given :
John can play 12 songs on his guitar but learns 1 new song every week. Aiden can play 4 songs but learns 2 every week.
To Find :
How many weeks will it be before Aiden knows as many songs as john?
Solution :
Let, after x weeks Aiden know a songs and John know j songs.
The linear equation for both the situation is :
a = x + 12 .....( For Aiden )
j = 2x + 4 ......( For John )
We need to find in which week Aiden knows as many songs as John.
For this , a = j
x + 12 = 2x + 4
x = 8
Therefore, in 8th week both of them know the same number of songs.
how to find surface area of trapezoid.
Answer: To find the area of a trapezoid, start by adding together the length of the bases, which are the 2 sides of the trapezoid that are parallel with each other. Then, multiply that number by the height of the trapezoid. Finish by dividing the product by 2 to find the area. Or check this image it can help u

From the set {24, 36, 72}, use substitution to determine which value of x makes the inequality true. A. 72 B. 36 C. none of these D. 24
Complete question :
From the set {24, 36, 72}, use substitution to determine which value of x makes the inequality true.
x ÷ 12 < 3
Answer:
24
Step-by-step explanation:
Given the inequality : x ÷ 12 < 3
Substitute the values in the set for X and test the inequality expression if it hoods true for each of the substituted value.
x = 24
24 ÷ 12 < 3
2 < 3 (true)
x = 36
36 ÷ 12 < 3
3 < 3 (false)
x = 72
72 ÷ 12 < 3
6 < 3 (false)
find the discriminant of 2x square + x - 6 is equal to zero?
Answer:
When the discriminant value is zero, we get one real solution; When the discriminant value is negative, we get a pair of complex solutions; Standard Form. The standard discriminant form for the quadratic equation ax 2 + bx + c = 0 is. Discriminant, D = b 2 – 4ac. Where. a is the coefficient of x 2. b is the coefficient of x. c is a constant term.

Answer: (0.-7)
Step-by-step explanation:
Take the equation
y=x-7
The last number 7 is the Y-intercept
(0.-7)
Answer:
(0,-7)
Step-by-step explanation:
Hey There!
So we can easily find which one is a solution but taking an order pair and plugging in the x value
then we solve for y and if we get the value of y that is with the matching x value then it is a solution
for example for the first pair we plug in -1 to x
-1-7=-8
-8 does not equal -6 therefore the first one is not a solution
for the second one we plug in 0 to x
0-7=-7
-7=-7 therefore it is a solution
but lets just check the rest to be safe
for the third one we plug in 8 to x
8-7=1
-1 does not equal 1 thus it is not a solution
for the last one we plug in -1
-1-7=-8
-8 does not equal 6 therefore it is not a solution
so we can conclude that the second one is a solution
IM BEGGING PLEASE HELP One angle of the triangle is 30% larger than the other and 36 ° smaller than the third. Find the angles of the triangle.
9514 1404 393
Answer:
52°, 40°, 88°
Step-by-step explanation:
Let x represent "one angle". This is 30% larger than "the other", so we have ...
x = "the other" × (1 +30%)
x/1.30 = "the other"
If x is 36° smaller than the third, then the third is x+36.
__
The sum of the angles is 180°.
x + x/1.3 + (x +36) = 180
x(2 +1/1.3) = 144
x = 144/(2 +1/1.3) = 52
x/1.3 = 52/1.3 = 40
x +36 = 88
The angles of the triangle are 52°, 40°, and 88°.
