A triangle that has no two right angles is called a scalene triangle.  If the triangle has two right angles, it is called isosceles triangle. A triangle with equal sides is called an equilateral triangle.

Suppose the length of each side of a
Ilya [14]

Answer:

The original side length of the square was 9 ft

Step-by-step explanation:

Consider that the square was initially of side length "x" (our unknown). Then the sides were all increased by 5 ft, and now the perimeter (addition of all four sides) of the square render 56 ft.

Let's write an equation that represents the addition of the four sides of this new rectangle, and set it equal to 56 ft. Then solve for the unknown "x":

(x+5)+(x+5)+(x+5)+(x+5)=56\\x+x+x+x+5+5+5+5=56\\4x+20=56\\4x=56-20\\4x=36\\x=9

Therefore, the original side of the square was 9 ft.

Б) 3х2 – 10 = 152<br>how to solve with square root​
Tju [1.3M]

Answer:

3\sqrt{6}  and  -3\sqrt{6}

Step-by-step explanation:

We will take numbers to one side and variables to one side eliminate the "Square" with "Square Root" and solve for the variable x. The process is shown below:

3x^2-10=152\\3x^2=152+10\\3x^2=162\\x^2=\frac{162}{3}\\x^2=54\\x=\sqrt{54}

Now, we need to reduce the radical by using the rule shown below:

\sqrt{x*y}=\sqrt{x}  \sqrt{y}

Now,

\sqrt{54}=\sqrt{6*9} =\sqrt{6}  \sqrt{9} =3\sqrt{6}

The correct answer is  3\sqrt{6} and -3\sqrt{6}

<u>Note:</u> squaring positive and negative makes the same answer

photoshop1234 [79]

The median number of telephone line in thousands is 0

The number of telephone lines in each country = 250000

From the given dot plot

The data set will be

0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 250, 250, 250, 250, 250, 500, 750, 750, 1000, 1000, 1250, 1750

The median of the data set is the middle term of the ordered data set. The order of the data set maybe ascending or descending order

There are 28 terms in the data set the middle terms will be 14th and 15th

Both 4th and 15 terms are 0

Therefore, the median is 0
