Let f(x) = 2x, g(x) = 2x^2 – x, and h(x) = 3x. lola finds the composition [f o g o h](x) as shown below. what error did lola make?
= 2[2(3x)^2 – 3x]
= 2[2(9x^2) – 3x]
= 2(18x^2 – 3x)
= 36x^2 – 3x

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

the ratios are reciprocals im positive

step-by-step explanation:

they are all positive numbers so it wouldn't be the other ones
