Remark
You can use a method called unit analysis to solve this problem. You will use it many times in your education later on.

Now sort out the numbers in the numerator and those in the denominator and multiply them together.
<em><u>Numerator</u></em> 28 * 5280 * 1 * 1 = 147840
<em><u>Denominator:</u></em> 60 * 60 = 3600
Now divide the numerator by denominator
Answer = 147840 / 3600 = 41.1 Feet / second
28 miles per hour = 41.1 feet / second
When we say conjecture, in math, this is defined as a statement that appears to be true but is not yet proven. Now, the question asked for the counterexample, which means, the opposite of the given statement above. Rectangle, rhombus and square are considered parallelograms. Therefore, the figure that can serve as a counterexample to the conjecture given is the TRAPEZOID. The answer would be option D.
that doesn't make sense I'm sorry
Answer: 80
Step-by-step explanation:
Answer:
2x/(x+3) +3/(x-3) = 8/(x^2
[2x(x-3) +3(x+3)]\( x^2 - 9) =8/(x^2 -9)
2x^2 -6x +3x +9=8 (x^2 -9) /(x^2 -9)
2 x^2 -3x +9 -8=0
2 x^2 -3x +1 =0
2x^2 -2x -1x +1 =0
2x(x-1) -1(x-1)=0
(x-1)(2x-1)=0
either, or, 2x-1=0
x-1 =0 2x =1
x =1 x= 1/2
hence, x= 1, 1/2
