Answer: 4x(2x+3).

Step-by-step explanation: To factor a number means to break it up into numbers that can be multiplied together to get the original number. In the given problem, we can factorize the expression by taking out a common factor, in this case 4x:

$8x^{2} +12x=$

$4x(2x+3)$

as we can see, if we multiply 4x*(2x+3) we obtain the original expression.

Answer:

$4x(2x + 3)$

Step-by-step explanation:

We have the expression

$8x^2 + 12x$

and we must factor it

Note that the expression has no independent term

Then we can factor the expression by taking the variable 4x as a common factor

$8x^2 + 12x$

$4x(2x + 3)$

Finally the factored form of $8x^2 + 12x$ is $4x(2x + 3)$

What is the area of rhombus ABCD? Enter your answer in the box. Do not round at any steps. put the answer in units²

AlladinOne [14]

Answer:

Therefore the Area of Rhombus ABCD is 36 unit².

Step-by-step explanation:

Given:

ABCD is a Rhombus

A = (-1,0)

B = (5,-3)

C = (-1,-6)

D = (-7 ,-3)

To Find:

Area of Rhombus ABCD = ?

Solution:

We know that Area of Rhombus is given as

$\textrm{Area of Rhombus}=\dfrac{1}{2}\times d_{1}\times d_{2}$

Where ,

d₁ and d₂ are the Diagonals.

We have,

Diagonals as AC and BD,

Using Distance Formula we get

$l(AC) = \sqrt{((x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} )}$

Substituting coordinates A and C we get

$l(AC) = \sqrt{((-1-(-1))^{2}+(-6-0)^{2} )}=\sqrt{36}\\l(AC)=6\ unit$

Similarly for BD we have,

$l(BD) = \sqrt{((5-(-7))^{2}+(-3-(-3))^{2} )}=\sqrt{144}\\l(BD)=12\ unit$

Now Substituting AC and BD in Formula we get

$\textrm{Area of Rhombus}=\dfrac{1}{2}\times AC\times BD$

$\textrm{Area of Rhombus}=\dfrac{1}{2}\times 6\times 12=36\ unit^{2}$

Therefore the Area of Rhombus ABCD is 36 unit².

Square root<br><img src="https://tex.z-dn.net/?f=%20%5Csqrt%7B121%20%7D%20" id="TexFormula1" title=" \sqrt{121 } " alt=" \sqrt{1

wariber [46]

Answer:

$11$

Step-by-step explanation:

The number inside the square root symbol is the number you have to get when you multiply a certain number twice.

So $\sqrt{121}$ :

What multiplied by itself is 121?

Backwards equation:

$121 / 11$

$==> 11$

Do not do the backwards method all the times, it does not work for all numbers.
