gulaghasi [49]

      x² - 8x = 65
      x² - 8x + 16 = 65
   x² - 8x + 16 - 65 = 65 - 65
      x² - 4x - 4x + 16 - 65 = 0
x(x) - x(4) - 4(x) + 4(4) - 65 = 0
      x(x - 4) - 4(x - 4) - 65 = 0
   (x - 4)(x - 4) - 65 = 0
   (x - 4)² - 65 = 0

It is actually (x - 4)² - 65.

16. Find the perimeter and area of a rectangle with length 6ft. and width 4 ft.

Andreas93 [3]

P = (L+W)*2
⇒ P= (6+4)*2
⇒ P= 10*2
⇒ P= 20.

S= L*W
⇒ S= 6*4
⇒ S= 24

The perimeter and area of the rectangle is 20 ft and 24 ft^2 respectively~

Which represents the inverse of the function f(x) = 4x?

wel

The inverse of the funtion f(x) = 4x

 f(x) = 4x
y = 4x
Swap out x with y
x = 4y
x / 4 = y
y = x / 4
$f(x)^{-1} = \frac{x}{4}$

Looks like none of the answer you have given are correct.
