This is = 4 therefore no property is applied
Answer: 19.6 feet
Step-by-step explanation:
Using the Pythagorean theorem,

A line is 180°, so the supplementary angel makes up the difference between. 180 - 60 = 120°
Answer:
y = -1
Step-by-step explanation:
Notice that the line x = 9 is a vertical line, therefore a line perpendicular to it will be a horizontal line of the form y = constant number.
Since we want it to go through the point (9, -1), then we know that that y value needs to be "-1", and the equation of the line will be given by the expression:
y = -1
Answer:
The answer to your question is the second choice
Step-by-step explanation:
4x/ (x - 7) - (x +7) / x
- Find the greatest common factor from x and (x - 7)
GCF = x(x - 7)
- Substract the terms
[4x(x) - (x + 7)(x - 7)] / x(x - 7)
- Simplify
[ 4x² - x² + 49] / x(x - 7)
[ 3x² + 49] / x(x - 7)
- Result
3x² + 49 / x(x - 7)
