If you would like to simplify <span>5 + 2{x - 4[3x + 7(2 - x)]}, you can do this using the following steps:
</span>
5 + 2{x - 4[3x + 7(2 - x)]} = 5 + 2{x - 4[3x + 7 * 2 - 7x]} = 5 + 2{x - 4[-4x + 14]} = 5 + 2{x - 4 * (-4)x + (-4) * 14} = 5 + 2{x + 16x - 56} = <span>5 + 2x + 2 * 16x - 56 * 2 = 5 + 2x + 32x - 112 = 34x - 107
The correct result would be </span><span>34x - 107.</span>
Equation: x² - 15x = 16
Factors: x = -16 and x = 1
Given
A number squared minus fifteen times the number is equal to 16.
<u>Equation</u>: x² - 15x = 16
Factors:
x² - 15x - 16 = 0
So,
(x - 16) (x + 1)
=> x - 16 = 0, x + 1 = 0
= x = -16 and x = 1

Answer:
Each octave change requires a doubling of the frequency.
Therefore, one octave above 126.63 is 126.63 * 2 which equals
