A rectangular packet of drink has a width that is 2 cm less than its length.

snow_lady [41]

Answer:

$6m^2+8m-16$

Step-by-step explanation:

Given that the length of the packet is $l=m$ cm.

Then the width being 2cm less than the length becomes $w=m-2$ and the height being 4 cm more than its length becomes $h=m+4$

The total surface area of the rectangular packet is given by:

$T.S.A=2(lw+lh+wh)$

$\implies T.S.A=2[m(m-2)+m(m+4)+(m-2)(m+4)]$

We expand to get:

$\implies T.S.A=2(m^2-2m+m^2+4m+m^2+4m-2m-8))$

$\implies T.S.A=2(3m^2+4m-8)=6m^2+8m-16$

The function p(x) = - 2(x-9)2 + 100 is used to determines the profit on T-shirts sold for x dollars. What would the profit from

dolphi86 [110]

ANSWER

$28

EXPLANATION

The profit function is given as:

$p(x) = - 2 {(x - 9)}^{2} + 100$

where x is the price of the T-shirt in dollars.

To find the profit on a T-shirt whose price is $15, we substitute x=15 into the function and simplify.

$p(15) = - 2 {(15 - 9)}^{2} + 100$

We simplify to get:

$p(15) = - 2 {(6)}^{2} + 100$

$p(15) = -72+ 100$

$p(15) = 28$
