Which equation results from taking the square root of both sides of (x 9)2 = 25? x 3 = ±5 x 3 = ±25 x 9 = ±5 x 9 = ±25.
The equation which is results from taking the square root of both sides of the provided equation is,
[tex](x+9)=\pm5\\[/tex]
What is the square root?A square root of a number is the value which is when multiplicand by itself gives the same value as the number posses.
Let a number is a. Then this number in the form of square root can be written as,
[tex]a=\sqrt{a}\times \sqrt{a}[/tex]
The given algebraic equation in the problem is,
[tex](x+ 9)^2 = 25[/tex]
Take the square root, in both sides,
[tex]\sqrt{(x+ 9)^2} = \sqrt{25}\\\sqrt{(x+ 9)^2} = \sqrt{5^2}[/tex]
Cancel out the square root with the square of the number as,
[tex](x+9)=\pm5\\[/tex]
Hence, the equation which is results from taking the square root of both sides of the provided equation is,
[tex](x+9)=\pm5\\[/tex]

Perimeter of the given polygon is equals to 64cm.
What is perimeter?
"Perimeter is defined as the total distance around the given shape."
Theorem used
Tangents drawn from a exterior point of a circle have equal length.
According to the question,
As shown in the diagram,
P, Q, R, and S are exterior points of a circle through which tangents are drawn.
Given,
Length of tangent PA = 13cm
Length of tangent SA= 9cm
Length of tangent RC = 4cm
Length of tangent QC =6cm
As per stated theorem we get,
Length of tangent PB = 13cm
Length of tangent SD 9cm
Length of tangent RD = 4cm
Length of tangent QB =6cm
Perimeter of a given polygon = 13 +13 +9+9+4+4+6+6
= 64cm
Hence, perimeter of the given polygon is equals to 64cm.

Karen has a red ribbon that is 18 feet long and the blue ribbon that is Sophie long she wants to cut both ribbons into pieces that are all the same length and she wants to have no ribbon left when she's done what is the greatest length in feet of a piece of ribbon that she can cut
Answer:
6feet
Step-by-step explanation:
THIS IS THE COMPLETE QUESTION BELOW:
Karen has a red ribbon that is 18 feet long and a blue ribbon that is 12 feet long. She wants to cut both ribbons into pieces that are all the same length and she wants no ribbon leftover when she is done. What is the greatest length in feet, of each piece of ribbon that she can cut?
Here the question is only talking about the GREATEST COMMON FACTOR that exist between 12 and 18. Since we are told that She wants to cut both ribbons into pieces that are all the "THE SAME LENGHTH"
For the ribbon that of 18 feet long, it can only be cut into 3pieces of equal Lenght i.e(18/6)= 3 pieces
For the ribbon that of 12 feet long, it can only be cut into 2pieces of equal Lenght i.e(12/6)= 3 pieces
Therefore the greatest common factor which divide both 12 and 8 is 6. which means 6 is the greatest length in feet, of each piece of ribbon that she can cut

Create a line segment that is exactly 10 units in length and has a midpoint of (-3,4)
Answer: A segment AB with Endpoints A (-8, 4) and B (2,4) is a horizontal line segment with (-3,4) as the midpoint.
A segment CD with endpoints C(-3,9) and D(-3,-1) will create a vertical line segment with (-3,4) as the midpoint.
A line segment FG with endpoints F (-6,0) and G(0,8) is a diagonal line with a slope of 4/3 and its midpoint is (-3,4)
Step-by-step explanation: For a horizontal or vertical line segment, choose the x-value or the y value of the midpoint. subtract 5 to get the lower endpoint, add 5 to get the higher endpoint. Keep the other coordinate the same.
The diagonal line segment is based on the hypotenuse of a triangle with side lengths corresponding to the Pythagorean Triple 3,4,5 Add and subtract 3 to the x-value od the midpoint, add and subtract 4 to the y value of the midpoint and the hypotenuses will extend 5 units in both directions from the midpoint.

Answer:
Proper fractions with a denominator of 6: 1/6, 2/6, 3/6, 4/6, 5/6.
Step-by-step explanation:
A proper fraction means that the numerator is less than the denominator.
Examples of this are 1/3, 3/4, 2/7.
Since the denominator must be 6, hence the answers are 1/6, 2/6, 3/6, 4/6, 5/6.
We know that the number line is in 12ths. In addition, we know that 6ths are 1/2 of 12. Thus, we put a proper fraction on every other line on the number line.

The admission fee at an amusement park is $1.50 for children and $4 for adults. On a certain day, 301 people entered the park, and the admission fees collected totaled 814 dollars. How many children and how many adults were admitted? Your answer is number of children equals number of adults equals
Answer:
156 children145 adultsStep-by-step explanation:
Let number of adults be a and children be c
Then we have equations
a + c = 3014a + 1.5c = 814From the first equation we get a = 301 - c, we substitute a in the second equation:
4(301 -c) + 1.5c = 8141204 - 4c + 1.5c = 8142.5c = 1204 - 8142.5c = 390c = 390/2.5c = 156Then finding the value of a:
a = 301 - 156 = 145The ratio of the number of girls to the number of all students in the class is 4 to 9. Can there be 20 students in that class?

A garden contains 135 flowers, each of which is either red or orange. There are 50 orange flowers. If R represents the number of red flowers in the garden, what equation could you use to find the value of R?
Answer:
85/135 -> 17/27.
50/135 -> 10/27.
Step-by-step explanation:
135 - 50 orange = 85 R.
50 O + 85 R = 135 total.
85/135 -> 17/27.
50/135 -> 10/27.
