The formula for the perimeter of a rectangle is p=2l 2w. solve for w. w=p−2l/2 w=2p/l w=p 2l w=2p−l

TiliK225 [7]

$p=2l+2w\ \ \ \ \ |subtract\ 2l\ from\ both\ sides\\\\2w=p-2l\ \ \ \ |divide\ both\ sides\ by\ 2\\\\\boxed{w=\dfrac{p-2l}{2}}$

Mary has 36 flower pots. She plants in 2/3 of her flower pot. In how many flower pots does mary plant daisies?

Mariana [72]

Answer: 24

Step-by-step explanation:

36/3 = 12

This means that 12 is one third of the flower pots.

Since she uses two thirds, just multiply the answer by 2.

12x2 = 24, so 2/3 is 24

Therefore, Mary plants daisies in 24 flower pots.

Hope this helps!

a piece of wire 48 m long is bent into the shape of a rectangle whose length is twice its width. find the length of the rectangl

Drupady [299]

$\bf \textit{perimeter of a rectangle}\\\\
P=2(L+w)~~
\begin{cases}
L=length\\
w=width\\[-0.5em]
\hrulefill\\
L=\stackrel{twice~the~width}{2w}\\
P=48
\end{cases}\implies 48=2(2w+w)\implies \cfrac{48}{2}=3w
\\\\\\
24=3w\implies \cfrac{24}{3}=w\implies \boxed{8=w}
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
L=2(8)\implies L=16$
