The length of a rectangle is twice it’s width.The perimeter of the rectangle in 162 inches.How long is the rectangle?

Artist 52 [7]

The perimeter of a rectangle is all sides added up, so length + length + width + width.

L = length

W = width

then the perimeter is L+L+W+W, or 2L + 2W, or 2(L+W).

$\bf \textit{perimeter of a rectangle}\\\\
P=2(L+W)~~
\begin{cases}
P=162\\
L=\stackrel{\textit{twice W}}{2W}
\end{cases}\implies 162=2(2W+W)
\\\\\\
\cfrac{162}{2}=3W\implies 81=3W\implies \cfrac{81}{3}=W\implies 27=W$

what's the length? well, is just 2(27).

Which equation represents h(x)?

Lelechka [254]

Answer: The second choice: h(x) = (f(x))(g(x))

Step-by-step explanation:

f(x) = -15

g(x) = 15

h(x) = -225

-15 * 15 = -225

Therefore, h(x) is the distribution of f(x) and g(x).

NemiM [27]

1 Acre = 43560 square feet
1 Ton = 2000 pounds

320 Acres = 320 * 43560 square feet = 13939200 = 1393.92 * 10,000

1393.92 *40 pounds needed = 55756.8
55756.8 / 2000= 27.8784
