Step-by-step explanation:
given
, x ≠ - 1
The x ≠ - 1 means that x cannot take the value of - 1 as this would make the denominator equal to zero which would make the fraction undefined.
Factor the numerator/ denominator
8x² - 8 = 8(x² - 1) ← factor out 8 from both terms
x² - 1 ← is a difference of squares, hence
8x² - 8 = 8(x - 1)(x + 1)
4x + 4 = 4(x + 1) ← factor out 4 from both terms
Thus the fraction now simplifies to
Cancel the 8 and 4 by 4 and cancel the factor (x + 1), leaving
= 2(x - 1) = 2x - 2 ← in the form ax + b

Answer:
Step-by-step explanation:
The diagram of the right angle triangle is shown in the attached photo.
From the given right angle triangle,
AC represents the hypotenuse of the right angle triangle.
With m∠32 as the reference angle,
BC represents the adjacent side of the right angle triangle.
AB represents the opposite side of the right angle triangle.
To determine BC, we would apply
the Sine trigonometric ratio which is expressed as
Sin θ= opposite side/hypotenuse. Therefore, the expression used to find BC is
Sin 32 = BC/9
BC = 9Sin32
