Answer:

<h2>8 units²</h2>

Step-by-step explanation:

Let side of the square = a

The , Area of square = a²

Now, Midpoint of Diagonal DB is E

And DE = 2 units

So, DB = 2 DE = 2 × 2 = 4 units

Now, using Pythagoras theorem in ∆ BCD

DB² = DC² + BC²

plug the values

${4}^{2} = {a}^{2} + {a}^{2}$

Collect like terms

${4}^{2} = 2 {a}^{2}$

Evaluate the power

$16 = 2 {a}^{2}$

Swipe the side of the equation

$2 {a}^{2} = 16$

Divide both sides of the equation by 2

$\frac{2 {a}^{2} }{ 2 } = \frac{16}{2}$

Calculate

${a}^{2} = 8$

Therefore, The area of the square is 8 sq.units.

Hope this helps..

Question:

Solution:

Let the following equation:

$\sqrt[]{12-x}=\text{ x}$

this is equivalent to:

$(\sqrt[]{12-x})^2=x^2$

this is equivalent to:

$12-x=x^2$

this is equivalent to:

$x^2+x-12=\text{ 0}$

thus, we can conclude that

x= 3.

(14x2 - 3x3 + 9x4) - (-14 + 13x3 + 11x4) simplify and answer in standard form

FromTheMoon [43]

We have that
(14x2 - 3x3 + 9x4) - (-14 + 13x3 + 11x4)=14x2 - 3x3 + 9x4 +14 - 13x3 - 11x4
(14x2 - 16x3 +14 - 2x4)

then
-2x4-16x3+14x2+14=0--------------> this is the standard form

simplify dividing the entire expression by two
-x4-8x3+7x2+7=0

the answer is
-x4-8x3+7x2+7=0

Which of the following is true for this graph? Will give brainliest to correct answer.

vlabodo [156]

its B because all the other ones don't make sense for the graph and you just do the slope and it is -3
