The answer is 6 root 2

Answer:

x = \sqrt{6}

Step-by-step explanation:

Since the given triangle is equilateral the all 3 sides would be:

\sqrt{6} +\sqrt{6} or \sqrt{12}. Now we know that the base of the right triangle is \sqrt{6} and the hypotenuse is \sqrt{12}. Therefore we can say;

A² + B² = C²

(\sqrt{6})² + x² = (\sqrt{12})²

6 + x² = 12

x² = 12 - 6

x² = 6

x = \sqrt{6}

Therefore; <u>x = </u>\sqrt{6}<u> is the length of x</u>, in simplest radical form.

X^2 - 25 = 25 solve for x
Nezavi [6.7K]

Answer:

\tt x=\pm5\sqrt{2}

Step-by-step explanation:

\tt x^2 - 25 = 25

\tt x^2-25+25=25+25 (Add 25 to both sides)

\tt x^2=50 ( Take square of both sides)

\tt x=x=\sqrt{50},\:x=-\sqrt{50}

\tt x=\pm5\sqrt{2}

How do you solve this?
kkurt [141]

Answer:

B. 28.1

Step-by-step explanation:

By the property of intersecting secant and tangent out side of the circle.

20 \times (20 + x) =  {31}^{2}  \\ 20(20 + x) = 961 \\ 20 + x =  \frac{961}{20}  \\ 20 + x = 48.05 \\ x = 48.05 - 20 \\ x = 28.05 \\  \huge \red{ \boxed{x = 28.1}}

Which inequality is shown in the graph?
sergij07 [2.7K]

Answer:

The answer to your question is: letter C

Step-by-step explanation:

Data

Find the Parabola's equation and express the equation as an inequality.

Vertex = (0, -5)

Equation

                               (x- h) ² = 4p(y - k)

                               x² = y + 5

                              y = x² - 5

But, we need the area upper the parabola, then

                              y ≥ x² - 5
