Answer:

C

Step-by-step explanation:

To solve, use inverse operations:

(x+6)^2=49\\\sqrt{(x+6)^2} =\sqrt{49} \\x+6=+/-7

Now we solve for both +/- 7.

x+6=7

x=1

x+6=-7

x=-13

You want to sell your house.Your realtor earns 6% of the selling price.Your house sells for 100,000.How much will your realtor e
sp2606 [1]
Hey there! :D

Let's assume that 100,000 is 100%. Now, we have to find what 6% of 100,000 is. 
We can do this step by step.
First, figure out what 1% of 100,000 is. To find 1% of a number, move the decimal place 2 places to the left. 
So, when we move the decimal 2 places to the left, we have 1000.00. Basically, we have 1000.
So, 1000 is 1% of 100,000. Now, to find 6%, multiply 1000 by 6. So, 1000 multiplied by 6 is 6000. The final answer is 6000. The realtor earns 6000 dollars.
Thank you! Hope it helped!

If each point in the diagram can act as an endpoint, how many distinct line segments can be formed using the set of points
sdas [7]

Answer:

Option D 6 is the answer.

Step-by-step explanation:

the given points are A, D, C and B. If each point in the diagram can act as end points, we have to calculate number of distinct line segments formed.

This ca be calculated in two ways.

(1) We will form the line segments

AB, AC, AD, BC, BD, DC

Therefore 6 segments can be formed.

(2) By combination method

Number of segments = ^{4}C_{2}

= \frac{4!}{2!2!}=\frac{4\times 3\times 2\times 1}{(2\times 1)\times (2\times 1)}

= \frac{4\times 3}{2\times 3}=\frac{12}{2}

= 6

Option D 6 is the answer.

Show that the triangle below is not a right-angled triangle.
Paha777 [63]

Step-by-step explanation:

A right triangle is a triangle in which one of the angles is a 90∘ angle.

(5x - 8)  + (2x - 5)  + (2x  + 3) = 180 \\ 9x - 10 = 180 \\ 9x = 190 \\ x =  \frac{190}{9}  \\ x = 21.11

(5x - 8) =97.56  \\ (2x - 5)  =37.22  \\ (2x + 3) =45.22  \\

Since None of the angels is 90° , so the triangle is not a right triangle.
