Answer:
4.625
Step-by-step explanation:
All you do is divide 15/24 and then add the four before the decimal, and BOOM there is your answer! Good Day!
A triangle angles all add up to 180 degrees and you have a 90 and 40 degree angle so you are at 130 degrees so the answer is B) x=50 degrees
The distance further the friend walked is 0.41 miles.
<h3>How much farther did the friend walk?</h3>
The distance the friend walked can be determined by calculating the circumference of a semicircle.
Circumference of a semicircle = πr + 2r
r = 0.25 / 2 = 0.125mi
3.14 x 0.125 + 0.25 = 0.66 mi
Difference in the distance = 0.66 - 0.25 = 0.41 miles

Answer:
see explanation
Step-by-step explanation:
1
Given
2x² - 16 = 0 ( add 16 to both sides )
2x² = 16 ( divide both sides by 2 )
x² = 8 ( take the square root of both sides )
x = ± 
= ± 2
------------------------------------
2
Given
- 5x² + 9 = 0 ( subtract 9 from both sides )
- 5x² = - 9 ( divide both sides by - 5 )
x² = 
( take the square root of both sides )
x = ± 
= ± 
-----------------------------------------
3
Given
6x² - 15 = 27 ( add 15 to both sides )
6x² = 42 ( divide both sides by 6 )
x² = 7 ( take the square root of both sides )
x = ± 
If -7x2 mean -7x^2, x^3, etc. Then the answer would be x5-x3-7x2+2 or the answer is B.
Hope this helped!
