Find the area of this rhombus

Vikentia [17]

<h2>Hello!</h2>

The answer is:

The area of the rhombus is equal to 64 squared inches.

$area=64in^{2}$

Since we already know half of the length of the diagonals of the rhombus, we can calculate the area of the rhombus using the following formula:

$area=\frac{diagonal_{1}*diagonal_{2}}{2}$

From the image we can see that:

$diagonal_{1}=8in+8in=16in$

$diagonal_{2}=4in+4in=8in$

So, substituting, we have:

$area=\frac{16in*8in}{2}=\frac{128in^{2} }{2}=64in^{2}$

Hence, we have that the area of the rhombus is equal to 64 square inches.

Have a nice day!

The area of a rectangle is x 2 – 3x – 28. If the<br><br>length is x + 4, find the width.

Hatshy [7]

Answer:

-4 square units

Step-by-step explanation:

a = l × b

x2 - 3x - 28 = (x +4)(×)

x2 - 3x - 28 = x2 + 4x

-3x - 28 - 4x = 0

-7x - 28 = 0

-7x = 28

x = -4

Show that a sequence {sn} coverages to a limit L if and only if the sequence {sn-L} coverages to zero.

Andreyy89

Let ${s_n}_{n\in\Bbb N}$ be a sequence that converges to $L$ . This means for any $\varepsilon>0$ , there is some $N$ such that $|s_n-L|$ for all $n>N$ . From this inequality we see that $|(s_n-L)-0|$ , so it follows that $s_n-L\to0$ .

On the other hand, let ${s_n-L}$ be a sequence that converges to 0. This means $|(s_n-L)-0|$ for all large enough $n$ , and we get the simpler inequality for free, $|s_n-L|$ , so it follows that $s_n\to L$ .
