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

1 answer:

6 0

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).

. How do we write simple expressions using long & synthetic division? Explain

igomit [66]

Answer:

For not exact divisions: Writing the results as Quotient + Remainder over the Divisor.

For exact division: just the quotient.

Step-by-step explanation:

Hi there,

In both algorithms, for long and synthetic divisions we must write the result as an expression following that order:

$Dividend: Divisor=Qx+\frac{Rx}{Dx}$
