Answer:

D

Step-by-step explanation:

We could plug x into the equation but to make it easier we simplify it first

\frac{1}{x} -\frac{1}{x+1}

-\frac{1}{x+1} + \frac{1}{x}

-\frac{1}{2x+1}

x = -1/2

-2-2 = -4

Choose the numbers that are factors of 112. (Hint: Use the divisibility rules to help you!) 2 3 4 6 7 8
Svetlanka [38]

Divide 112 by the possible answers. If the answer comes out even it is a factor. If it comes out with a decimal it is not a factor:


112 / 2 = 56, so 2 is a factor.

112/3 = 37.333., 3 is not a factor.

112 /4 = 28, 4 is a factor.

112 / 6 = 18.66, 6 is not a factor.

112 / 7 = 16, 7 is a factor.

112/8 = 14, 8 is a factor.


The factors are: 2 , 4 ,7 and 8.

Pleasseee help me with this.it’s life or death
barxatty [35]

Answer:

(a) 4 miles

(b) 8.9 miles

Step-by-step explanation:

(a) Theorem 1: In a right triangle, the altitude drawn from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of the altitude is the geometric mean of these two segments.

Hence, the distance d between the park and the library is

d^2=2\cdot 8\\ \\d^2=16\\ \\d=4\ miles

(b) Theorem 2: In a right triangle, the altitude drawn from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of each leg of the right triangle is the geometric mean of the lengths of the hypotenuse and the segment of the hypotenuse that is adjacent to the leg.

Thus, the distance D between the park and the football field is

D^2=8\cdot (2+8)\\ \\D^2=8\cdot 10\\ \\D^2=80\\ \\D=\sqrt{80}=4\sqrt{5}\approx 8.9\ miles
