We are given that the shorter piece is x
From your description, the longer piece is 2x + 2
The total length is
x + 2x + 2 = 14
ie
3x + 2 = 14
3x = 12
x = 4
So the length of the shorter piece is 4 ft
Therefore the length of the longer piece must be
(14 - 4) ft = 10 ft
Simple, just multiply 2x1=2. And then add the remaining zeros to the end, which would make it 20,000.
Answer:
The current area of the circle is 81π in².
They want to " 'decrease' " the radius to 9 in.
First, find the current radius for the current circle.
Areas of circle = πr²,
81π = πr²
First, divide π from both sides of the equation:
(81π)/π = (πr²)/π
r² = 81
Isolate the variable, r. Root both sides of the equation:
√(r²) = √(81)
r = √( 9 * 9) = 9
The radius currently is 9 in.
The NBA is not making any changes at all, therefore the question will be void. (Note that the other answer choice is -9, however, you cannot have a negative measurement, therefore, the answer is voided).

0.9 is a rational number since the decimal stops at 9, it's not infinite.
18 is an integer and a whole number. They have the same meaning.
0.6 is a rational number.
12x-5+85=128.......12x+80=128......12x+80-80=128-80....12x=48...... divide both sides by 12 to get x=4. Now most people do not complete solving for the missing value....12(4)-5=43 degrees
