If x =3+2 root 2 find x - 1/x
Answer:
-2+2[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Since we have the value of x, 3+2[tex]\sqrt{2}[/tex], we can plug that value into the new equation.
We would recieve (3+2[tex]\sqrt{2}[/tex]-1)/3+2[tex]\sqrt{2}[/tex]
Which could simplify to -2+2[tex]\sqrt{2}[/tex]
[tex]x-\dfrac 1x\\\\\\=3+2\sqrt 2- \dfrac 1{3+2\sqrt 2}\\\\\\=3+2\sqrt 2 - \dfrac{3-2\sqrt2}{\left(3+2\sqrt 2\right) \left(3-2\sqrt 2 \right)}\\\\\\=3+2\sqrt 2 -\dfrac{3-2\sqrt 2}{3^2 - \left(2\sqrt 2 \right)^2}\\ \\\\=3+2\sqrt 2-\dfrac{3-2\sqrt2}{9-8}\\\\\\=3+2\sqrt 2-3+2\sqrt 2\\\\\\=4\sqrt2[/tex]

The length of a rectangle is three times it’s width if the perimeter of the rectangle is 80m find it’s area
Answer:
=3y^2
Step-by-step explanation:
let,
length: x
width: y
According to condition,
x = 3y -----------(1)
Second condition
Perimeter = 2 (l + b)
80 = 2 (x + y)
x + y = 40 -------------(2)
To find area,
Area = L x B
=3y x y
= 3y^2

Write an equation and solve:
An iced cake costs 10p more than a plain cake. Sarah bought two of each cake. They cost £1 altogether. What is the cost of an iced cake?
Answer:
55p
Step-by-step explanation:
iced cake = 10p more than a plain cake
iced cake = 10p + plain cake
iced cake and a plain cake together = £1
iced cake + plain cake = £1
if iced cake = 10p + plain cake, we can plug this into our second formula to get
(10p + plain cake) + plain cake = £1
10p + 2 * plain cake = £1 = 100p
subtract 10p from both sides to isolate the variable and its coefficient
2 * plain cake = 90p
divide both sides by 2 to isolate the variable
plain cake = 45p
iced cake = 10p + plain cake = 55p

Which expression is equivalent to n5 • k5 • n-5 • k?
a. N^5 k
b. N^-25 k^5
c. K^6
d. (nk)^6
The expressions are algebraic expressions, and the equivalent expression of n⁵ * k * n⁻⁵ * k is k⁶
How to determine the equivalent expression?The expression is given as:
n⁵ * k⁵ * n⁻⁵ * k
Rewrite the expression as:
n⁵ * k * n⁻⁵ * k = n⁵ * n⁻⁵ * k⁵ * k
Apply the law of indices
n⁵ * k * n⁻⁵ * k = k⁶
Hence, the equivalent expression of n⁵ * k * n⁻⁵ * k is k⁶

Find the diameter of the circle with the given circumference. Use 3.14 for pi . C=18 cm
Answer:
[tex]d=\frac{18}{\pi }[/tex]
Step-by-step explanation:
We work our way backward to find the diameter.
Circumference of a Circle Formula:
[tex]C=2\pi r[/tex]
r is radius , 2*radius = diameter.
Given information: C=18 cm , pi=3.14.
[tex]C=2\pi r\\18=2\pi r\\[/tex]
Get r by itself.
[tex]r=18/2\pi\\r=9/\pi[/tex]
r≈2.864788976
2*r=d
[tex]2*9/\pi =diameter\\d=\frac{18}{\pi }[/tex]

[tex]\frac{2x}{x+5}[/tex]
Step-by-step explanation:
We are given a function for f and g, and are asked to find f/g.
We know f = 4x^2 + 6x and g = 2x^2 + 13x + 15
Simply put function of f over g.
[tex]\frac{4x^2+6x}{2x^2+13x+15}[/tex]
Factor:
[tex]\frac{2x(2x+3)}{(2x+3)(x+5)}[/tex]
Since both numerator and denominator have 2x + 3, we can cancel them out.
[tex]\frac{2x}{x+5}[/tex] is our answer.

What is the range?
2 ,9 ,7 ,9 ,1 ,6
Answer:
8Step-by-step explanation:
The range is the difference between the highest and lowest values in a data set.
Highest value = 9Lowest value = 1Range = 9 - 1 = 8Answer:
8
Step-by-step explanation:
When finding the range, you have to subtract the smallest value from the biggest value,
2, 9, 7, 9, 1, 6
⇒ 1, 2, 6, 7, 9, 9
If we take a look at the set of numbers, we can see that 1 is the smallest value and 9 is the biggest,
Now that know that we need to subtract,
9 - 1
= 8
Therefore the range of this set of numbers is 8.
