Question:
Solution:
Let the following equation:
![\sqrt[]{12-x}=\text{ x}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B12-x%7D%3D%5Ctext%7B%20x%7D)
this is equivalent to:
![(\sqrt[]{12-x})^2=x^2](https://tex.z-dn.net/?f=%28%5Csqrt%5B%5D%7B12-x%7D%29%5E2%3Dx%5E2)
this is equivalent to:

this is equivalent to:

thus, we can conclude that
x= 3.

<h2>Question</h2>
What is Quadrilateral!?
<h2>Answer</h2>
a quadrilateral can be defined as a closed, two-dimensional shape that has four straight sides. ✔
Step-by-step explanation:
<h3>
Here are examples of Quadrilaterals</h3>
The seven types of quadrilaterals are parallelogram, rhombus, kite, rectangle, trapezoid, square, and isosceles trapezoid. ✔
<h3>Properties</h3>
<em>The sides do not have to be the same length. Quadrilaterals have four sides, four vertices, and four interior angles that add up to 360</em>°✔
Therefore, I hope this helps! ツ

Answer: Linear model
and H'(t) = 9 units.
Step-by-step explanation:
Since we have given that
In 2000, amount spent = $100 billions
In 2010, amount spent = $190 billions.
So, rate of increase would be

So, linear model for H(t) would be

So, H'(t) would be 9.
Hence, linear model
and H'(t) = 9 units.
Answer:
Hypotenuse of first triangle is 7.61
Hypotenuse of second triangle is 45
Step-by-step explanation:
Given that:
Triangle 1:
a = 3
b = 7
Using Pythagorean theorem;
a²+b²=c²

Taking square root on both sides

c = 7.61
Hypotenuse is 7.61
Triangle 2:
a = 27
b = 36
Using Pythagorean theorem;
a²+b²=c²

Taking square root on both sides

c=45
Hypotenuse is 45
Hence,
Hypotenuse of first triangle is 7.61
Hypotenuse of second triangle is 45
