Answer:

Yes, it is true for all values of x.

Step-by-step explanation:

We have given the equation:

(x²-3x+2)/(x-1) = x-2

First we solve the nominator L.H.S by factorization method.

x²-3x+2=0

x²-x-2x+2=0

x( x-1)-2( x-1)= 0

(x-1)(x-2)=0

Putting the value of nominator of L.H.S in the equation we get,

(x-1)(x-2)/(x-1)= (x-2)

Simplifying it we get,

(x-2) = (x-2)

Hence, L.H.S = R.H.S

So, it is true for all values of x.

Answer:

It is true for all values of x

Step-by-step explanation:

\frac{(x^2-3x + 2)}{x-1} = x - 2

\frac{(x^2-3x + 2)}{x-1} = x-2

First lets simplify Left hand side

LHS = \frac{(x^2-3x + 2)}{x-1}

Solving the numerator of LHS

x² - 2x - x +2

Using factorization to simplify

x(x-2) - 1(x-2)

(x-1)(x-2)

LHS becomes

\frac{(x-1)(x-2)}{x-1}

(x-1) will cancel out

LHS = (x-2)

LHS = RHS

x-2 = x-2

It is evident from the above expression that \frac{(x^2-3x + 2)}{x-1} = x - 2 is true for all values of x

Sherry has a package in the shape of a rectangular prism. What is the volume, in cubic inches (in.), of the rectangular prism? (
Rudiy27

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the dimension of the prism is not given. However, the following steps can serve as a guide for you.

The volume of a rectangular prism is calculated as thus:

Volume = Length * Width * Height

So, Take for instance

Length = 2\ in

Width = 3\ in

Height = 4\ in

The Volume would be:

Volume = 2\ in * 3\ in * 4\ in

Volume = 24\ in^3

The perimeter of a regular hexagon is 6x + 30. What is the length<br> of each side of the hexagon?
Fofino [41]

Answer:

x + 5

Step-by-step explanation:

This is actually rather simple to figure out. Simply divide 6x + 30 by 6. That should get x + 5 for the length of one side.

Pls help me i will make u brainest

Answer:

12 sapphires

Step-by-step explanation:

Let's call the number of sapphires x. This means the number of rubies is the total number of gems minus x, or 17-x.

# of Sapphires: x

# of Rubies:17-x

A sapphire is worth 5 (gold coins) each, and a ruby is worth 8.

We also know the total amount of money is 100 coins, so

5*x+8*(17-x)=100

5x+136-8x=100

-3x=-36

x=12

Remember:

# of Sapphires: x

# of Rubies:17-x

...so Lara found 12 sapphires and 17-12=5 rubies.

Pls hurry the answer is not 36.......Given a * b=ba−ba+ab, find (2*3)×(3*2).
Nataly_w [17]

Answer:

36

Step-by-step explanation:

In the above question, we have been given a rule to follow

Given a * b = ba−ba+ab

We are to find (2*3)×(3*2)

Let simplify each bracket first

a * b = ba−ba+ab

2*3, a = 2, b = 3

2*3 = 3×2 - 3×2 + 2×3

= 6 - 6 + 6

= 6

a * b = ba−ba+ab

3*2, a = 3, b = 2

3*2 = 2×3 - 2×3 + 3×2

= 6 - 6 + 6

= 6

(2*3)×(3*2)

= 6 × 6

= 36

The answer is 36
