f ( x ) mean : " f is a function of x " f ( 1.5 ) are value of FUNCTION 3 x - 2 when x = 1.5 so of f ( 1.5 ) = 2.5
Algebra
f ( 1.5 ) = 3 * 1.5 - 2 = 4.5 - 2 = 2.5 Answer : A

If 3m 66m mean 3 m 66 cm then: 3 m 66 cm = 3.66 m L = Longer piece S = Shorter piece L = 2 S L + S = 3.66 m 2 S + S = 3.66 m 3 S = 3.66 m Divide both sides by 3 S = 3.66 m / 3 S = 1.22 m = 1 m 22 cm L = 2 S = 2 * 1.22 m = 2.44 m = 2 m 44 cm
