Step-by-step explanation:

\frac{x + 4}{3 {x}^{2}   - 12x - 96}  =  \frac{x + 4}{3( {x}^{2} - 4x - 32) }  =  \frac{x + 4}{3(x - 8)(x + 4)}

=  \frac{1}{3(x - 8)}  =  \frac{1}{3x - 24}

8x - 20

Step-by-step explanation:

3(x - 6) + 4 + 5x - 6         \longmapsto       Distribute 3 to (x - 6)

3(x) - 3(6) + 4 + 5x - 6

3x - 18 + 4 + 5x - 6

Simplify:

3x + 5x - 18 + 4 - 6

8x -18 - 2

Express the following vector in the form v=v1i+v2j+v3k. 3u - v if u=(4,7,-3) and v=(2,-7,5).3u - v = ____ i + ____ j + _____ k.(
Alecsey [184]

Answer:

<h2><em>5i+14j-7k</em></h2>

Step-by-step explanation:

Given the vectors u = (4,7,-3) and v=(2,-7,5), both vectors are 3-dimensional in nature and can also be rewritten as;

u = 4i+7j-3k and v = 2i-7j+5k

To get 3u-v, we will substitute the given vectors into the expression;

3u-v = 3(4i+7j-3k) -  (2i-7j+5k)

open the parenthesis

3u-v = 12i+21j-9k - 2i + 7j - 5k

collect like terms

3u-v = (12i - 2i) + (21j + 7j) (-9k-5k)

3u - v = 10i+28j-14k

To simplify the answer, we will divide through by 2

3u - v = 10i/2+28j/2-14k/2

<em>3u - v = 5i+14j-7k</em>

<em>Hence the simplified form of the expression is 5i+14j-7k</em>
