Find the error with this proof and explain how it mat be corrected in order to clearly prove the equation.

enyata [817]

Answer:

Step-by-step explanation:

It is true that for any given odd integer, square of that integer will also be odd.

i.e if $m$ is and odd integer then $m^{2}$ is also odd.

In the given proof the expansion for $(2k + 1)^{2}$ is incorrect.

By definition we know,

$(a+b)^{2} = a^{2} + b^{2} + 2ab$

∴ $(2k + 1)^{2} = (2k)^{2} + 1^{2} + 2(2k)(1)\\(2k + 1)^{2} = 4k^{2} + 1 + 4k$

Now, we know $4k^{2}$ and $4k$ will be even values

∴ $4k^{2} + 1 + 4k$ will be odd

hence $(2k + 1)^{2}$ will be odd, which means $m^{2}$ will be odd.

The area of a rectangle is 5/8 meter. The length of the garden is 1/5 meter. What is the width of the rectangle?

Afina-wow [57]

Width of rectangle is $Width=\frac{25}{8} meters$

Step-by-step explanation:

Area of rectangle = $\frac{5}{8}$

Length of garden = $\frac{1}{5}$

Width of rectangle = ?

Using the Formula:

Area = Length * Width

Putting values and finding width:

$\frac{5}{8}=\frac{1}{5}*Width\\ Width=\frac{5}{8}\div\frac{1}{5}\\Width=\frac{5}{8}*\frac{5}{1}\\Width=\frac{25}{8} meters$

So, width of rectangle is $Width=\frac{25}{8} meters$
