Which choice is equivalent to the product below for acceptable values of X?
sqrt(x+2)*sqrt(x-2)
Answers
Answer:
√x^2-4
Step-by-step explanation:
Given the expression
√(x+2) * √(x-2)
= √(x+2)(x-2)
Expand
= √x(x)-2x+2x-2(2)
= √x^2-4
Hence the product of the expression will give √x^2-4
For x to be acceptable x^2 - 4 = 0
x^2 = 4
x = ±√4
x = ±2
Acceptable value of x are values that are greater than or equal to ±2
Answer:
√x^2-4

Answers
Answer:
50
Step-by-step explanation:
We know angles in a straight line add up to 180, therefore:
2x + 50 + 30 = 180
2x + 50 = 180 - 30
2x + 50 = 150
2x = 150 - 50 = 100
2x = 100
x = 50
Answer:
Step-by-step explanation: Since we know the angle of a line is 180 degrees. We can use that.
1. 180-30 because we already know that angle is 30 degrees.
2. We are left with 150 degrees so we know the large angle is 150 degrees to check we do this.
3. 150=2x+50
4. 100=2x Divide both sides by two and get
5. x=50

Consider the figure shown below, find the value of
g
Answers
Given:
A figure of a triangle.
To find:
The value of g.
Solution:
Law of Cosines:
[tex]a^2=b^2+c^2-2bccosA[/tex]
Using the Law of Cosines for the given triangle, we get
[tex]g^2=8^2+7^2-2(8)(7)cos(65^\circ)[/tex]
[tex]g^2=64+49-112(0.4226)[/tex]
[tex]g^2=113-47.3312[/tex]
[tex]g^2=65.6688[/tex]
Taking square root on both sides.
[tex]g=\sqrt{65.6688}[/tex]
[tex]g=8.10363[/tex]
[tex]g\approx 8.10[/tex]
Therefore, the value of g is about 8.10 units.
