Answer:
the measurements must be incorrect because when you solve it, it is obvious that 6x is not a 90 degree angle and 3x is not 45 degrees.
Step-by-step explanation:
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:2nd one
Step-by-step explanation:
Y=log5(x-5)
8 full rotations measures 5 meters.
That means 8 times the circumference is 5 meters.
Let C = circumference.
8C = 5
C = 5/8 = 0.625
The circumference measures 0.625 m.
The circumference is
Now we substitute our value into the circumference formula.
