sukhopar [10]

Answer:

The homeowner will require 9 strips of wallpaper.

Step-by-step explanation:

The question is asking <em>"how many 20 inches fit into 15 feet?".</em>

We know that

1 foot = 12 inches;

therefore, 15 feet will be

15 ft * 12 in/ft = 180 in.

Now, the number of 20 inches wallpaper strips that will fit into 180 in long wall will be

180 in/ 20 in = 9

Therefore, the homeowner will require 9 strips of wallpaper.

( −2 x^3) ^ 3 simplify

densk [106]

Answer:

$-8x^9$

Step-by-step explanation:

We can split up the exponent into multiple products: $(-2x^3)^3=(-2)^3*(x^3)^3$ .

We know that $(-2)^3=(-2)*(-2)*(-2)=-1*-1*-1*2*2*2=-1*8=-8$ .

We also know that $(x^3)^3=x^{3*3}=x^9$ .

So, our answer is $\boxed{-8x^9}$ and we're done!
