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.

Expand.<br> Your answer should be a polynomial in standard form.<br> (3c + 2)(c^2-6c-4)

evablogger [386]

Answer:

After expanding the polynomial $(3c + 2)(c^2-6c-4)$ we get $3c^3-16c^2-24c-8$

Step-by-step explanation:

We need to expand the polynomial $(3c + 2)(c^2-6c-4)$

Multiply the terms:

$(3c + 2)(c^2-6c-4)\\=3c(c^2-6c-4)+2(c^2-6c-4)\\=3c^3-18c^2-12c+2c^2-12c-8\\=3c^3-18c^2+2c^2-12c-12c-8\\=3c^3-16c^2-24c-8$

So, after expanding the polynomial $(3c + 2)(c^2-6c-4)$ we get $3c^3-16c^2-24c-8$
