How to simplify a given expression?

The given expression can be simplified by eliminating the common terms from the denominator and numerator. By doing this, the expression can be simplified.

The given expression is:

$(x^(2)-1 )/(x^(2)-x)$

It can be simplified as shown below:

$(x^(2)-1 )/(x^(2)-x) = ((x+1)(x-1 ))/(x(x-1))$

The numerator is split using the identity :

$a^(2) -b^(2) =(a+b)(a-b)$

It can be further simplified as follows:

$(x^(2)-1 )/(x^(2)-x) = ((x+1)(x-1 ))/(x(x-1))\n= (x+1)/(x) \n=(x)/(x) +(1)/(x) \n= 1+(1)/(x)$

We have simplified the given expression into 1 + 1/x.

Thus, the expression x^2-1 / x^2-x in its simplest form is 1 + 1/x.

Answers

V = Bh

B = area of the base of the triangles

Area of the triangle = hb/2 = (8ft * 5ft)/2 = 40ft² / 2 = 20 ft²

V = 20 ft² * 4 ft = 80 ft³

At the theater, one section of seats has 8 rows with 12 seats in each row. In the center of each of the first 3 rows are 4 broken seats that cannot be used. How many seats can be used in the section?

Answers

92 because 8*12 is 96. Then, you have to do 96 - 4 which is 92.

Final answer:

Initially, we have 96 seats in the theater. However, due to 12 broken seats in the first 3 rows, 84 seats are usable.

Explanation:

To answer this question, we will use simple multiplication and subtraction techniques of Mathematics. This is about calculating the number of workable seats in a theater.

First, we need to calculate the total number of seats in the theater. There are 8 rows with 12 seats in each row. We multiply the number of rows by the number of seats in each row: 8 rows * 12 seats/row = 96 seats.

In the first 3 rows, there are 4 broken seats in each of these rows. We need to subtract these from the total number of seats: 3 rows * 4 broken seats/row = 12 broken seats.

Finally, we subtract the number of broken seats from the total number of seats to find out how many seats can be used: 96 seats - 12 broken seats = 84 usable seats.
