Simplify

• (x-9)/(x+9)

• 1/(x-9)

• (x+9)

• 1/(x+9)

Answer explanation

To simplify (x-9)/(x+9), we can factor out a common factor of 1 from the numerator, resulting in 1/(x-9). Therefore, the correct choice is 1/(x-9).

Multiply and Simplify 

• 4(x+3)/(x+2),

• (x+2)/4(x+1)

• (x+2)/4(x+3),

• 4(x+1)/(x+2), 

Answer explanation

To multiply and simplify, we get (4(x+3))/(x+2) = 4(x+3)/(x+2). Therefore, the correct answer is (x+2)/4(x+1).

Multiply and Simplify 

• 2(x+8) / (x-2)

• (x-2)

• (x+4) / (x-6)

• (x-4) / (x+8)

Answer explanation

To multiply and simplify 2(x+8) / (x-2), we get 2x + 16 / (x-2), which simplifies to (2x + 16) / (x-2), further simplifying to 2(x+8) / (x-2), which is equal to (x-2).
