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).

If y=x^2 and x=(-8) then y =...
lutik1710 [3]

Answer:

-64

Step-by-step explanation:

If

y=x^2

and the x represents -8

Your answer will be -64

By saying that x=(-8)   all you have to do is plug in the negative 8 to the original equation of y=x^2. This would make it   y=(-8)^2

When you plug in negative 8 to the second power into the calculator your answer will be -64

I hope this helps king!
