Box-and-whisker plot
We are given the box-and-whisker plot that summarizes the magnitude of earthquakes.
The minimum value of the dataset is 2,5
The maximum value of the dataset is 8.5
The range is the difference:
Range = 8.5 - 2.5 = 6
Range = 6
P = 4a.....this is the perimeter of a square
P = 4(180)
P = 720 ft
and if the spray cost 0.11 per ft......720 * 0.11 = 79.20 rounded to the nearest dollar is $ 79 <==
_C because multiply 2X times f(x) Kansas X out to make it zero Sony multiply -4 times X it will leave you with a positive four instead since X times X
The corrects answers are B and D for this one.
Since you divide the same side for both the the rectangles on both parts and if the division statements are equaled, then they are similar.
For example;
Answer B.
50 / 10 = 5
and
30 / 6 = 5
Answer D.
7.5 / 2.5 = 3
and
4.5 / 1.5 = 3
Since they both equal the same for both of the rectangles for the answers individually, they are similar polygon rectangles.
Hope this helps!

Answer:
x = 0 or x = 1/2 and x = -1 for the second equation
Step-by-step explanation:
Solve for x:
4 x^2 - 2 x = 0
Factor x and constant terms from the left hand side:
2 x (2 x - 1) = 0
Divide both sides by 2:
x (2 x - 1) = 0
Split into two equations:
x = 0 or 2 x - 1 = 0
Add 1 to both sides:
x = 0 or 2 x = 1
Divide both sides by 2:
Answer: x = 0 or x = 1/2
_______________________________
Solve for x:
x^2 + 2 x + 1 = 0
Write the left hand side as a square:
(x + 1)^2 = 0
Take the square root of both sides:
x + 1 = 0
Subtract 1 from both sides:
Answer: x = -1
