<span> 3x^2 – 4x – 4 = 0

</span>

<span>multiply the first coefficient by the last coefficient: </span>

<span>3 x -4= -12 </span>

<span>Now think, what adds to the 2nd coefficient (-4) and multiplies to -12? </span>

<span>-6 and 2 </span>

<span>rewrite your equation: </span>

<span>3x^2 - 6x + 2x - 4 <==== this is essentially the same equation </span>


<span>now split it... </span>

<span>3x^2 - 6x </span>

<span>AND </span>

<span>2x -4 </span>

<span>factor each one so that both share a common factor: </span>

<span>3x(x-2) </span>

<span>AND </span>

<span>2(x-2) </span>

<span>Now combine them: </span>

<span>(3x+2)(x-2) </span>

By applying the law of sines and some algebraic handling, the length of the side LJ is approximately equal to 3.517 units. (Right choice: D)

<h3>What is the missing side of the triangle according to the law of sines?</h3>

The law of sines presents a relationship between sides and <em>opposite</em> angles, which is described below:

9/sin 89° = LJ/sin 23°     (1)

LJ = 9 × sin 23°/sin 89°

LJ ≈ 3.517

By applying the law of sines and some algebraic handling, the length of the side LJ is approximately equal to 3.517 units. (Right choice: D)

A small company 's net income for the first 6 months of the year was 76.500 and for the last six months it was 100,000 . What is
inna [77]

Answer:The ratio of net income in the first 6 months, to the last six months is $76,500 / $100,000. This simplifies intuitively as follows:

76500/100000

Dividing by 100: 765/1000

Dividing by 5: 153/200

The denominator 200 is only divisible by the prime numbers 2 and 5, and since the numerator 153 is not divisible by either 2 or 5, this means that this is in simplest form, and the final answer is 153/200.

Step-by-step explanation:i did the research for you this isnt my own answer therefore don't give me the credit. but hope this helped you tho :D
