Maria has a business designing and making custom T-shirts. Her cost for materials, in thousands of dollars, is given by M(t)=−3

Lady_Fox [76]

Answer:

$P(t) = -t^2 + 12t$

Step-by-step explanation:

Given

$M(t) = -3t^2 + 36t$ -- Cost

$S(t) = -4t^2 + 48t$ --- Income

Required

Determine P(t)

P(t) is calculated as:

$P(t) = Income - Cost\\$

$P(t) = S(t) - M(t)$

$P(t) = -4t^2 + 48t -(-3t^2 + 36t)$

Open bracket

$P(t) = -4t^2 + 48t +3t^2 - 36t$

Collect Like Terms

$P(t) = 3t^2 -4t^2 + 48t- 36t$

$P(t) = -t^2 + 12t$

Factor to solve:<br>x² + 18x +27 = 8x +3

patriot [66]

Answer: $x=-4$ $or$ $x=-6$

<u>Subtract 8x+3 from both sides</u>

<u></u> $x^2+18x+27-(8x+3)=8x+3-(8x+3)$ <u></u>

<u></u> $x2+10x+24=0$ <u></u>

<u></u>

<u>Factor left side of equation</u>

<u></u> $(x+4)(x+6)=0$ <u></u>

<u></u>

<u>Set factors equal to 0</u>

<u></u> $x+4=0$ $or$ $x+6=0$

Final Answer: $x=-4$ $or$ $x=-6$
