Jimmy owns a small engine repair business. The revenue, in dollars, can be modeled by the equation y = 420 + 72x, where x is the
kozerog [31]

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.

<em>So, x = 5 hours</em>

Okay so what we know is that there are 6 sides.
—————-————————————————————

3separate groups have the same measurements. So really 3 groups of 2 that have the same measurements.
—————————————————————
2 sides are 3*2 —————>an area of 6
2 sides are 3*2—————>an area of 6
2 sides are 2*2—————>an area of 4
—————————————————————so, we add those #s up and get 6+6+4 which equals 16 as your answer.
