Answer:
(x - 1)( x - 2) (x + 2) = x³ -x² -4x + 4.
Explanation:
1) Given equation:
3 5x x + 2
- ------- + -------- = ---------------
x + 2 x - 1 x² - 3x + 2
2) So, the denominators are x + 2, x - 1, and x² - 3x + 2
3) The LCD is the product of the common and non common factors raised to the greatest power.
4) x + 2, and x - 1 are already prime factors
5) Factor x² - 3x + 2
x² - 3x + 2 = (x - 2)(x - 1)
6) Then, the factors are x + 2, x - 1, and x - 2, and the LCD is the product of them:
(x - 1)( x - 2) (x + 2)
7) If you expand the products (distributive property) you get:
x³ -x² -4x + 4.
The answer to this question is:
x = 1 + or - the square root of 47
Answer:

The length of the shadow is 124.7 in
<u>Explanation:</u>
Angle of sun to the ground, θ = 30°
Height of the fence, h = 72 in
Length of the shadow, l = ?
We know,
tan θ = (Perpendicular)/(Base)
So,
tan 30° = 
Therefore, the length of the shadow is 124.7 in
