What are the solution(s) to the quadratic equation 50 - x2 = 0?

Mathematics
1 answer:
Vilka [71]3 years ago
6 0

Answer:

x = ± 5\sqrt{2}

Step-by-step explanation:

Given

50 - x² = 0 ( add x² to both sides )

x² = 50 ( take the square root of both sides )

x = ± \sqrt{50} = ± \sqrt{25(2)} = ± 5\sqrt{2}

What’s the perimeter of this rectangle 2,5+D and 4-1,3D
koban [17]

Answer:

The result can be shown in multiple forms.

Exact Form:

2,5+D,4-1,3D

Decimal form;

2,5+D,3,3D

Step-by-step explanation:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

What is the height of the tree
Margarita [4]

Answer:

16.5 m

Step-by-step explanation:

Hi there!

Set up a proportion (letting h = the height of the tree):

\displaystyle \frac{6 ft}{8 ft} = \frac{h}{22}

Multiply both sides by 22 to isolate <em>h</em>:

6/8 * 22 = h

h = 16.5

Therefore, the height of the tree is 16.5 m.

I hope this helps!
