Rational Numbers
It says that between any two real numbers, there is always another real number. Rational Numbers: Any number that can be written in fraction form is a rational number. This includes integers, terminating decimals, and repeating decimals as well as fractions.
Step-by-step explanation:
The angles (8x + 28) and (4x - 7) are supplementary to each other so we can write
or
Also, note that the angle (4x - 7) and 
are vertical angles, which means that they are equal to each other. Therefore,
Perimeter would be affected by the same scale factor, in this case 2. perimeter only has 1 dimension.
Answer: increas by a factor of 2

Step-by-step explanation:
Answer:
2 numbers could be 10 and 12
or - 12 and - 10
Step-by-step explanation:
let the 2 numbers be x and x + 2
since they are 2 consecutive even numbers, the difference between them is 2
the difference between the reciprocals is 1/60
we have to mulitply the 2 denominators x and (x+2) to get a common denominator for the 2 fractions
=
we can then remove the brackets from the numerator and denominator
and then cross multiply
60 * 2 = x² + 2x
120 = x² + 2x
x² + 2x - 120 = 0
we have a quadratic equation which needs to be solved
x² + 12x - 10x - 120 = 0
x (x + 12) - 10(x + 12) = 0
(x - 10) (x + 12) = 0
x - 10 = 0 or x + 12 = 0
x = 10 x = -12
