Factor the expression. 36y^2 – 84y – 147

Y_Kistochka [10]

If you would like to factor the expression 36y^2 - 84y - 147, you can do this using the following steps:

36y^2 - 84y - 147 = 3 * (12y^2 - 28y - 49) = 3 * (6y + 7) * (2y - 7)

The correct result would be b. 3 * (6y + 7) * (2y - 7).

Answer:

5 hours

Step-by-step explanation:

Given

$y = 420 + 72x$ --- Revenue

$y = 24x^2 + 180$ --- Overhead cost

Required

Determine the hours for break even

To do this, we simply equate both expressions as follows:

$24x^2 + 180 = 420 + 72x$

Collect Like Terms

$24x^2 - 72x + 180 - 420 = 0$

$24x^2 - 72x -240 = 0$

Divide through 24

$x^2 - 3x - 10 = 0$

Expand:

$x^2 -5x + 2x -10 = 0$

Factorize:

$x(x -5) + 2(x -5) = 0$

$(x + 2)(x -5) = 0$

$x + 2 = 0\ or\ x - 5 = 0$

$x = -2\ or\ x = 5$

But x can't be negative because it represents time.

So, x = 5 hours
