If x= 7 - 4√3 then find the value of (a) (x+1/x) rais to 2 b) x rais 2+1/x rais to 2

ololo11 [35]

The equation x = 7 - 4√3 is a radical expression, and the value of the radical expression is $(x + \frac 1x)^2 = 3650401 -2107560\sqrt 3$

<h3>How to solve the expressions?</h3>

The equation is given as:

x = 7 - 4√3

So, we have:

$(x + \frac 1x)^2 = (7 - 4\sqrt 3 + \frac{1}{7 - 4\sqrt 3})^2$

Take the LCM

$(x + \frac 1x)^2 = (\frac{49 -56\sqrt3 + 48}{7 - 4\sqrt 3})^2$

Evaluate the like terms

$(x + \frac 1x)^2 = (\frac{97 -56\sqrt3 }{7 - 4\sqrt 3})^2$

Rationalize

$(x + \frac 1x)^2 = (\frac{(97 -56\sqrt3)(7 - 4\sqrt 3) }{49 -48})^2$

Evaluate the difference

$(x + \frac 1x)^2 = ((97 -56\sqrt3)(7 - 4\sqrt 3))^2$

Expand

$(x + \frac 1x)^2 = (679 -388\sqrt 3 -392\sqrt 3 + 672)^2$

Evaluate the like terms

$(x + \frac 1x)^2 = (1351 -780\sqrt 3 )^2$

Expand

$(x + \frac 1x)^2 = 1825201 +1825200 -2107560\sqrt 3$

$(x + \frac 1x)^2 = 3650401 -2107560\sqrt 3$

Hence, the value of the radical expression is $(x + \frac 1x)^2 = 3650401 -2107560\sqrt 3$

What is the hcf of two coprime numbers

Karolina [17]

The HCF is the highest common factor of two numbers.

By definition, if two numbers are coprime, they have no common factors other than 1.

So, the highest (and only) common factor of two coprime numbers is 1.

The graph of f(x)=x2 is shown. Use the parabola tool to graph the function g(x)=(12x)2. To graph a parabola, first plot the vert

Talja [164]

Answer:

Pease check my assumptions.

Step-by-step explanation:

I will assume that f(x)=x2 is actually f(x) = x^2.

Same for g(x)=(12x)^2 [Is it g(x)=12x^2 ???]

See the attached image.

Note that (12x)^2 results in a narrower, steeper graph. That's because (12x)^2 can be rewritten as 144x^2, so every value is multiplied by 144, compared to just x^2.

The length of a rectangle is represented by x2 + 3x + 2, and the width is represented by 4x.

Amanda [17]

A: Perimeter = 2*length + 2*width = 2x^2 + 14x + 4

B: Area = length*width = 4x^3 + 12x^2 + 8x
