Write the equation
equation in standard form
X^2-1/X+1=2
Answer:
We start with the equation:
(x^2 - 1)/(x + 1) = 2
We want to rewrite this in standard form.
We can multiply both sides by (x + 1) to get:
((x^2 - 1)/(x + 1))*(x + 1) = 2*(x + 1)
x^2 - 1 = 2*(x + 1) = 2*x + 2
Now we can move all the terms to one side to get:
x^2 - 1 - 2 - 2*x = 0
x^2 - 2*x - 3 = 0
And this is a standard quadratic equation, that we can solve by using the Bhaskara's formula, this will give us the solutions:
[tex]x = \frac{-(-2) \pm \sqrt{(-2)^2 - 4*1*(-3)} }{2*1} = \frac{2 \pm 4}{2}[/tex]
Then the two solutions are:
x = (2 + 4)/2 = 3
x = (2 - 4)/2 = -1

Step-by-step explanation:
In a museum there is a sculpture in the shape of a cylinder. The cylinder has a diameter of 12 feet and a height of h feet. Which equation can be used to find V, the volume of the cylinder in cubic feet? Group of answer choices
The formula for the volume of a cylinder is = πr²h
From the above question:
Diameter = 12 feet
Radius = Diameter/2
= 12 feet/2 = 6 feet
Height = h
Hence:
Volume of the cylinder =
(π × 6² × h )cubic feet
= 36πh cubic feet
= 113.09733553h cubic feet
Approximately = 113.1h cubic feet

Paper clips are sold in boxes of 1000.
Each box costs £15.40
The table below shows the discount offered for large orders.
Ethan orders 5 boxes of paper clips.
Work out the amount of discount Ethan gets.
Answer:
6.5%
Step-by-step explanation:
1000 in a box and he orders 5 boxes.
1000x5= 5000
So he orders 5000 paper clips
1 box is £15.40 and he order 5, so £15.40x5= £77
£77 is between £55 and £79.99 so he will get 6.5% discount.
After the discount he will pay £71.99

which graph shows the solution to the system of equations?y =-2x+1 and y =-3/2
Answer:
(1.25, -1.5)
Step-by-step explanation:
The system of equations:
y = -2x + 1
y = -3/2
So we know that the two lines meet at the point where y = -3/2 = -1.5
∴ -1.5 = - 2x + 1
2x = 1 + 1.5 = 2.5
x = 2.5 ÷ 2 = 1.25
So the solution to this system of equation (or where the two lines meet) is the point (1.25, -1.5)

(2a²b)² +3(a²b)²-x²(-3ab)²
Answer:
7a^4b^2 -9a^2b^2x^2
Step-by-step explanation:
Given (2a²b)² +3(a²b)²-x²(-3ab)²
Recall that (xy)^a = x^a * y^a
Hence (2a²b)² +3(a²b)²-x²(-3ab)²
expanding the expression
= (2^2 *a^2+2 *b^2) + 3(a^2+2*b^2) - x^2(-3^2 * a^2b^2)
= 4a^4b^2 + 3a^4b^2 - x^2(9a^2b^2)
simplify
= 7a^4b^2 -9a^2b^2x^2
