If for x, real, f(x) = (x-1)^2 + (x-2)^2 + (x-3)^2, f(x+2) = ?
A. 3x^2 + 4x + 2
B. 3x
C. (x+2)^2 + x^2 + (x-2)^2
D. 3x^2 + 2

A. 3x^2 + 4x + 2 . ...

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

5 feet of chain cost $9

so the answer is 1.80
