<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>

Arnold can read 3 pages in 7 minutes. Brenda can read 8 pages in 14 minutes. Who is the faster reader? Justify your answer.
Mrac [35]

Answer:

Brenda

Step-by-step explanation:

You can divide the number of pages by the number of minutes to find the amount of minutes it takes to read 1 page. For Arnold, 3 pages / 7 minutes = 1 page per approximately 0.43 minutes. For Brenda, 8 pages / 14 minutes = 1 page per approximately 0.57 minutes. Brenda reads slightly faster since 0.57 > 0.43
