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)

*(The bottom part is x as it approaches infinity)*
Bess [88]

\bf \lim\limits_{x\to \infty}~\left( \cfrac{1}{8} \right)^x\implies \lim\limits_{x\to \infty}~\cfrac{1^x}{8^x}\\\\[-0.35em] ~\dotfill\\\\ \stackrel{x = 10}{\cfrac{1^{10}}{8^{10}}}\implies \cfrac{1}{8^{10}}~~,~~ \stackrel{x = 1000}{\cfrac{1^{1000}}{8^{1000}}}\implies \cfrac{1}{8^{1000}}~~,~~ \stackrel{x = 100000000}{\cfrac{1^{100000000}}{8^{100000000}}}\implies \cfrac{1}{8^{100000000}}~~,~~ ...

now, if we look at the values as "x" races fast towards ∞, we can as you see above, use the values of 10, 1000, 100000000 and so on, as the value above oddly enough remains at 1, it could have been smaller but it's constantly 1 in this case, the value at the bottom is ever becoming a larger and larger denominator.

let's recall that the larger the denominator, the smaller the fraction, so the expression is ever going towards a tiny and tinier and really tinier fraction, a fraction that is ever approaching 0.

A triangle has a base of 4 inches and a height of 6 inches. What is the area of the triangle? 10 in2 12 in2 20 in2 24 in2
xxMikexx [17]
The area of a triangle is represented by 1/2 x B x H, where B = base, H = height.


In this equation, B = 4, H = 6


1/2 x 4 x 6 = 12 in^2
