Answer:
66 feet
Step-by-step explanation:
Mayra wants to place tiles on the edge of pool, i.e, on the circumference of the circular part
so the length required will be ,2πr
radius=21/2 feet=10.5feet
now req lenght = (2π10.5)=66 (feet)
k-1/2b=47 because the difference is subtraction and half b is a half fraction and it equals 47.
A linear equation will contain a term in x has the highest degree. For example y = 2x - 5 . A non linear will contain terms with exponents 2 or higher
eg x^2 - 2x - 5 is nonlinear.
What you do here is subtract g from f: x^2 - 5x + 8 - (x^2 -4); x^2 - 5x + 8 - x^2 + 4; Rearranging gives you x^2 - x^2 - 5x + 8 + 4 which is, simplified, -5x + 12
The answer to the equation is 18 which is a composite whole number. the answer is C
