For all the non-negative numbers, the absolute value is always equal to the actual number.
If "x" is any non-negative number, then:
|x| = x
For all negative numbers, the absolute value is equal to -1 multiplied to that number.
If x is any negative number, then:
|x| = -x
So, if after subtracting 2 the number is not anymore equal to it absolute value, this means when 2 is subtracted the number changes from positive to negative.
Only one such number exists that changes from positive to negative on subtraction of 2 and that number if 1.
Absolute value of 1 is 1.
When 2 is subtracted from 1, the result is -1. The absolute value of -1 is also 1. So the absolute value is no longer equal to the original value.
The possible number that satisfies the given condition is 1.

Answer:
P = 60 cm
Step-by-step explanation:
To solve this question we will use the property of the tangents drawn from a point to a circle.
"Length of tangents drawn from a point to a circle are equal in measure."
By this property,
Therefore, BG ≅ FB ≅ 7.5 cm
AG ≅ AH ≅ 6.5 cm
CF ≅ EC ≅ 8.5 cm
Since m∠B ≅ m∠D
Therefore, length of tangents FB ≅ GB ≅ DE ≅ DH ≅ 7.5 cm
Since, Perimeter of ABCD = AB + BC + CD + DA
AB = 7.5 + 6.5 = 14 cm
BC = 7.5 + 8.5 = 16 cm
CD = 8.5 + 7.5 = 16 cm
DA = 7.5 + 6.5 = 14 cm
Now Perimeter = 16 + 16 + 14 + 14 = 60 cm
Therefore, P = 60 cm will be the answer.

I must assume that by "15x2 - 44x - 36" you actually meant "<span>15x^2 - 44x - 36." Use " ^ " to denote exponentiation, please.
One by one, take each of the following sets of possible factors and mult. them out to determine whether the result equals </span>15x^2 - 44x - 36:
<span>
(5x - 9)(3x + 4)
(3x - 4)(5x + 9)
(5x - 18)(3x + 2)
(5x + 18)(3x - 2)
First one: use the "foil" method: (5x)(3x) + 20x - 27x - 36. This does not simplify to </span>15x^2 - 44x - 36 and so is not the correct choice. Go on to the second answer choice and continue this check.
