Step-by-step explanation:
Here is the formulas 30-60-90 triangle: hypotenuse = 2short leg short leg = nhypotenuse/2 long leg = short leg√3 short leg = long leg/√3
It is an irrational number.
Irrational numbers can be written as a decimal but not a fraction. It has an endless non-repeating digits to the right of the decimal point.
Rational numbers are those that can be written as a ratio. Meaning it can be written as a fraction where both numerator and denominator are whole numbers.
Each term is double the one before it, so the appropriate choice is ...
... D. f(x+1) = 2f(x)
3.579 is greater.

Answer:
C
Step-by-step explanation:
3(3 + x) = 15 + x
Open bracket
9 + 3x = 15 + x
Collecting like terms
3x - x = 15 - 9
2x = 6
Dividing by 2
x = 6/2
x = 3
