Given f(x) = 2x + 1 and g(x) = 3x + 5, find h(x) = f(x) ∙ g(x).

h(x) = 5x + 6

h(x) = 6x2 + 13x + 5

h(x) = 6x2 + 7x + 5

h(x) = 10x + 12

The graph shows the decibel measure for sounds depending on how many times as intense they are as the threshold of sound. noise in a quiet room is 500 times as intense as the threshold of sound. what is the decibel measurement for the quiet room? 20 decibels28 decibels200 decibels280 decibels
