(2 + √3)(2 - √3)
x² - y² = (x + y)(x - y)x = 2, y= √3x² = 2² = 4y² = √3² = 3(2 + √3)(2 - √3) = 4 - 3 = 13.
(6 + √5)/(6 - √5)
Multiply both numerator and denominator by (6 + √5) to simplify(6 - √5) ((6 + √5) = 6² - √5² = 36 - 5 = 31(6 + √5)/(6 +√5) = 6² + 2*6*√5 + √5² = 36 + 12√5 + 5 = 41 + 12√5(6 + √5)/(6 - √5) = (41 + 12√5)/31Related Questions

Let f(x)=1/2x-3. Suppose you subtract 6 from the input of f to create a new function g, and then multiply the input of function g by 4 to create a function h. What equation represents h?
The equation for h is h(x)=?
PLZZZZ!! I NEED HELP ASAP!!!!
Answers
Answer: h(x)=2x-6
hope this helped
The value of h(x)= 2x- 36.
What is function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
f(x)=1/2x-3
Now, subtract 6 from the input of f to create a new function g
g(x)= 1/2x-3 -6
g(x)= 1/2x -9
and, multiply the input of function g by 4
h(x)= 4( 1/2x -9)
h(x) = 2x- 36
Hence, the value of h(x)= 2x- 36.

Write 80% as a decimal number and as a reduced fraction
Answers
Answer:
Decimal: 0.80 Reduced fraction: [tex]\frac{4}{5}[/tex]
Step-by-step explanation:
Take 80% and move the decimal two place values to the left.
This makes 0.80 (The decimal point is where the percent sign is.)
0.80 is [tex]\frac{8}{10}[/tex] because the 8 is in the tenths place value.
[tex]\frac{8}{10}[/tex] can be simplified by dividing both the numerator and the denominator by 2.
[tex]\frac{8}{10}[/tex] = [tex]\frac{4}{5}[/tex]

Answers
Answer:
2/6 or 33.33%
Explanation:
There are 6 numbers all together and 2 of them are 20$.As a fraction this would look like 2/6. 2/6 is also 33.33% of the wallet and its also the probability of pulling out a $20 bill
The probability that they are both $20 bill when There are two 20's, one 10, two 5's, and one 1 is to be considered as the 33.33%.
Calculation of the probability:
Since
You randomly choose two bills from your wallet.
And, there is 6 numbers
