Let breadth be x

  • Length=x+4

We know

\boxed{\sf Area_{(Rectangle)}=Length\times Breadth}

\\ \sf\longmapsto x(x+4)=22

\\ \sf\longmapsto x^2+4x=22

\\ \sf\longmapsto x^2+4x-22=0

  • By solving

\\ \sf\longmapsto x=-2\pm\sqrt{26}

It doesnot have any real roots

Answer:

j=3 inches

Step-by-step explanation:

Since the two triangles are similar, we can set up a ratio

1in:3in

j:9in

Now we solve for j

Since the length of the side of the shorter triangle is 1/3 the length of the side of the longer triangle (as shown by the ratio 1:3 which can also be written as 1/3), we can multiply 9 by 1/3. This gives us 3.

So j=3 inches

By what percent has the rhinoceros weight increased
romanna [79]

let's first off  convert those mixed fractions to improper fractions, then get their difference.

\bf \stackrel{mixed}{1\frac{1}{2}}\implies \cfrac{1\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{3}{2}}~\hfill \stackrel{mixed}{2\frac{1}{10}}\implies \cfrac{2\cdot 10+1}{10}\implies \stackrel{improper}{\cfrac{21}{10}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \cfrac{21}{10}-\cfrac{3}{2}\implies \stackrel{\textit{using the LCD of 10}}{\cfrac{(1)21-(5)3}{10}}\implies \cfrac{21-15}{10}\implies \cfrac{6}{10}\implies \cfrac{3}{5}

now, the original amount, 3/2, if that is the 100%, what is 3/5 off of it in percentage?

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2}\\ \frac{3}{2}&100\\\\ \frac{3}{5}&x \end{array}\implies \cfrac{~~\frac{3}{2}~~}{\frac{3}{5}}=\cfrac{100}{x}\implies \cfrac{3}{2}\cdot \cfrac{5}{3}=\cfrac{100}{x}\implies \cfrac{5}{2}=\cfrac{100}{x} \\\\\\ 5x=200\implies x=\cfrac{200}{5}\implies x=40
