The efficiency of a motor can be measured by the percentage of the input power that the motor uses. E(c) E(c)E, left parenthesis, c, right parenthesis models the efficiency (in percentage points) of a certain motor as a function of the power input's current c cc (in amperes).

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8

it would be r^2 - 2rs +s^2

assuming   you mean to square it
