Which of the following is the product of the rational expressions shown below ? (x + 3)/(x + 2) * (x - 3)/(x - 2)
Molodets [167]

Answer:

Option D : \frac{x^2-9}{x^2-4} is the correct answer.

Step-by-step explanation:

Given rational expression is:

\frac{x+3}{x+2}*\frac{x-3}{x-2}

In the first step of solving the rational expression, we will multiply the nominators and denominators.

\frac{(x+3)(x-3)}{(x+2)(x-2)}

\frac{x^2-3x+3x-9}{x^2-2x+2x-4}

Now we will solve the alike terms.

\frac{x^2-9}{x^2-4}

The product of rational expression is \frac{x^2-9}{x^2-4}

Hence,

Option D : \frac{x^2-9}{x^2-4} is the correct answer.

SOMEONE HELP ME PLEASE
OlgaM077 [116]

Step-by-step explanation:

If Angle 1 = 94°

Then

Angle 2 = 180°-94° = 86°

( Linear pairs or supplementary angles with angle 1 )

Angle 3 = 94°

( Corresponding angle with angle 1 )

Angle 4 = 86°

( Corresponding angle with angle 2 )

Angle 5 = 94°

( Exterior alternate angle with angle 1 or vertically opposite angle with angle 3 )

Angle 6 = 86°

( Alternate Interior angle with angle 2 or vertically opposite angles with angle 4 )

Angle 7 = 94°

( Alternate Interior angle with angle 3 and vertically opposite angles with angle 1)

Angle 8 = 86°

( Alternate exterior angle with angle 4 or vertically opposite angles with angle 2 )

Hope it helps you!!
