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]

Solve for g: C = 1/2gk
Answer:
G = [tex]\frac{C(2)}{k}[/tex]
Step-by-step explanation:
C = 1/2gk
First you want to multiple both sides by 2 to get rid of that fraction and you get
C (2) = gk then you divide both sides by k to isolate the g and your left with
G= [tex]\frac{C(2)}{k}[/tex]

Relflect the shape in the mirror line
Answer:
its hard to do this without a graph to draw on for you but see explanation
Step-by-step explanation:
from each point count how many units it is from the mirror line and then count that many in the opposite direction. for example, the top left point is 3 away from the mirror line from the left so count 3 units to the right of the mirror line and that is where that point will be.

Students in the Scott School District spent two weeks collecting a total of 5,853 books to donate to local hospitals. The first week, the students collected 2,054 books. About how many books did the students collect for the hospitals the second week? Choose the better estimate.
Answer:
3799 books
Step-by-step explanation:
We have the total number of books collected as 5,853 books
In the first week, a total of 2,054 books were collected.
If the collection of books went on for two weeks;
Hence in the second week, a total of (5,853 - 2,054) were collected.
Therefore, number of books collected in the second week = 3799 books

Use the table to find the residual points. A 4-column table with 5 rows. The first column is labeled x with entries 1, 2, 3, 4, 5. The second column is labeled given with entries negative 0.7, 2.3, 4.1, 7.2, 8. The third column is labeled predicted value with entries negative 0.28, 1.95, 4.18, 6.41, 8.64. The fourth column is labeled residual value with all entries blank. Which residual plot is the correct one for the data? A graph shows the horizontal axis numbered negative 1 to positive 7 and the vertical axis numbered negative 1.5 to positive 1.5. Points are scattered all over the graph. A graph shows the horizontal axis numbered negative 1 to positive 7 and the vertical axis numbered negative 1.5 to positive 1.5. Points are scattered all over the graph.

A graph shows the horizontal axis numbered negative 1 to positive 7 and the vertical axis numbered negative 1.5 to positive 1.5. Points are scattered all over the graph.
Answer:
B
Step-by-step explanation:
residual is the given - predicted
residual 1: -0.42
residual 2: 0.35
so on and so forth
B matches up with the first two coordinates
The residuals are 0.42, 0.35, -0.08, 0.79, and -0.65 because residuals are the difference between the actual and predicted.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
The residual = actual—predicted
We have given:
X Given Predicted Residual value
1 0.7 0.28 0.42
2 2.3 1.95 0.35
3 4.1 4.18 -0.08
4 7.2 6.41 0.79
5 8 8.65 -0.65
Thus, the residuals are 0.42, 0.35, -0.08, 0.79, and -0.65 because residuals are the difference between the actual and predicted.

- A rectangular pool has an area of 140 square feet. If the length of the
pool is 16 feet, what is its width?
Answer:
8.75 feet
Step-by-step explanation:
Use the area formula, A = lw, where l is the length and w is the width
Plug in the area and length, and solve for w:
A = lw
140 = 16w
8.75 = w
So, the width is 8.75 feet
Answer:
8.75 ft
Step-by-step explanation:
Use the area formula, A = lw, where l is the length and w is the width
Plug in the area and length, and solve for w:
A = lw
140 = 16w
8.75 = w
So, the width is 8.75 feet
17y-5x+8=9 in standard form?
Answer:
-5X + 17Y -1 A = -5X B = 17Y. C = -1
Step-by-step explanation:
follow me say a thanks mark me branliest
The equation of a line 17y - 5x + 8 = 9 in standard form
is - 5x + 17y - 1 = 0.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, 17y - 5x + 8 = 9 we have to convert in standard form Ax + By + c = 0.
∴ 17y - 5x + 8 = 9.
- 5x + 17y - 1 = 0.
So, A = - 5, B = 17 and, c = - 1.

Step-by-step explanation:
log(5x+10)-log(4x+12)=1-2log(3)
log(5x+10/4x+12)=1-2log(3)
log(5x+10/4x+12)=log(10)+log(3^-2)
