I assume that you mean 18s-27t

Let's go through each answer, and see which one is right.

A) 9 × 2(s-t)

Simplify that.

18(s-t)

18s-18t

So, A) is incorrect.

B) 9(2s-3t)

Simplify.

18s-27t

B) is the correct answer

C) 6(3s-4t)

Simplify.

18s-24t is incorrect because it is not equal to 18s-27

So, C) is incorrect.

D) 6 × 3(s-t)

Simplify.

18(s-t)

18s-18t

D) is incorrect.

So, your answer is B) 9(2s-3t)
