What is −2√20 − √125 in simplest radical form?
Answers
Answer:
Solving -5\sqrt{5} we get [tex]\mathbf{-9\sqrt{5}}[/tex]
Step-by-step explanation:
We need to solve [tex]-2\sqrt{20}-\sqrt{125}[/tex]
Factors of 20 are: 2x2x5
Factors of 125 are: 5x5x5
Replacing 20 and 125 with their factors.
[tex]-2\sqrt{20}-\sqrt{125}\\=-2\sqrt{2\times2\times5}-\sqrt{5\times5\times5}\\=-2\sqrt{2^2\times5}-\sqrt{5^2\times5}\\We \ know \ \sqrt{a^2}=a \\=-2\sqrt{2^2}\sqrt{5}-\sqrt{5^2}\sqrt{5}\\=-2\times2\sqrt{5}-5\sqrt{5}\\=-4\sqrt{5}-5\sqrt{5}\\Taking \ \sqrt{5} \ common\\=(-4-5)\sqrt{5}\\=-9\sqrt{5}[/tex]
So, solving -5\sqrt{5} we get [tex]\mathbf{-9\sqrt{5}}[/tex]

Answer:
No solution
Infinitely many solutions
One solution
Step-by-step explanation:
The first expression:
-2(3x - 1) = -6x -1
Expand the parentheses;
-6x + 2 = -6x -1
-6x + (-6x) = -1 -2
0 = -3
This problem has no solutions
Second expression:
2(3x-1) = 6x -2
Expand the parentheses;
6x - 2 = 6x -2
6x -6x = -2 + 2
0 = 0
This problem has infinitely many solutions
Third expression:
2(3x - 1) = -6x -2
Expand the parentheses;
6x -2 = -6x - 2
6x + 6x = -2 + 2
12x = 0
x = 0
This equation has only one solution
List the angles in order from smallest to largest.
smallest to largest
Options are U, T,S place in order smallest to largest
Answers
Answer:
T, S, U
Step-by-step explanation:
Answer:
U S T
Step-by-step explanation:
The largest angle is going to be opposite the longest side. It stands to reason that the two arms that define the enclosed angle (t) have to have their arms stretched further away from each other in order to accommodate T. So T is the largest angle.
By a similar line of reasoning, the second largest angle is opposite the second largest side. S is the second largest angle.
The smallest angle is opposite the smallest side.

Adam is building a rectangular planter without a top. The planter will be 14 cm wide, 20 cm long, and 30 cm high. How much wood is needed to make the bottom and sides of the planter? (show working as well)
Answers
Answer: The surface area of the planter will be 120.5 square feet.
Step-by-step explanation: in our shape, we will have 5 sides. The base and the four sides going up from each edge of the base.
The base will be 7 x 5 = 35 square feet.
The front and back side will each be 7 x 0.75 = 5.25 square feet.
The left and right side will each be 5 x 0.75 = 3.75 square feet.
If we add up the 5 faces we get:
35 + 5.25 + 5.25 + 3.75 + 3.75 = 120.5 square feet

What is the value of m? Please provide an explanation, thanks!
Answers
Answer:
∠m=124°
Explanation:
There are a few different ways that you could go about this but the simplest way is to first notice that Angle n is congruent to the angle above it. That tells us that n = 56 degrees. Because angle m and n are supplementary angles their sum needs to add up to 180. So if we subtract 56 from 180 we get 124 degrees, and there is your answer.
Hope this helps :)

Meredith
says that 15.17 is greater than 15.8
because 17 is greater than 8. Do you
agree? Explain your reasoning
Answers
Answer:
No
Step-by-step explanation:
Because in the number 15.8, it is equal to 15.80. 80 is more than 17.
15.17 is not greater than 15.8. Meredith statement is wrong.
What is Number system?A number system is defined as the representation of numbers by using digits or other symbols in a consistent manner.
We need to compare both the numbers 15.17 and 15.80.
For comparing two number we need to check the integer part and decimal part.
The integer part is same for both the numbers. so let us move towards decimal part. in tenth place 15.17 has 1 and for 15.80 it has 8.
We know that 8 is greater than 1.
Hence 15.8 is greater than 15.17. Merediths answer is wrong.

James completely covered a square poster board using 68.2 in. of cardstock. Which measurement is
closest to one side of the poster board in inches?
Answer?
Answers
Answer:
17inches
Step-by-step explanation:
If James completely covered a square poster board using 68.2 in. of cardstock, this means that the perimeter of the square box is 68.2in.
To get the measurement if one side if the box we will use the formula for finding the perimeter of the square.
P = 4L
L is side length of the square box
68.2 = 4L
L = 68.2/4
L = 17.05in
.hence the measurement closest to one side of the square box is 17inches

The image of (6, 9) under a dilation is (4, 6).
The scale factor of the dilation is ________.
Type a numerical answer in the space provided. If necessary, us the / key to represent a fraction bar.
Answers
Answer:
2/3
Step-by-step explanation:
The scale factor is the number that the original image is multiplied by to find the new image. So, we have to find what number multiplied by 6 equals 4 and what number multiplied by 9 equals 6. This can represented as an equation, with the unknown number represented by x:
6 * x = 4
6x = 4
Divide both sides by 6 to isolate x:
6x/6 =4/6
x = 4/6 = 2/3
x = 2/3
9x = 6
9x/9 = 6/9
x = 6/9 = 2/3
x = 2/3
For both dilations x came out to be 2/3. So, the scale factor is 2/3.
