A: l x w = a formula for area
l = w + 48 length
w(w+48) = 3024 substitute l with w+48
w^2 + 48w -3024=0 —solution to part A

B: w^2 + 48w - 3024 = 0 factor
(w-36)(w+84) = 0
Solutions for width = 36,-84
A width can’t be negative, so the width is 36 inches

In 2007, there were 31 laptops

abruzzese [7]

Answer:

$l=31+20(y-2007)$

where $l$ is the number of laptops, and $y$ is the year.

in 2017: $l=231$

Step-by-step explanation:

I will define the variable $x$ as the number of years that passed since 2007.

Since the school buys 20 lapts each year, after a number $x$ of years, the school will have

$20*x$ more laptops.

and thus, since the school starts with 31 laptops, the equation to model this situation is

$l=31+20*x$

where $l$ is the number of laptops.

since x is the number of years that have passed since 2007, it can be represented like this:

$x=y-2007$

where $y$ can be any year, so the equation to model the situation using the year:

$l=31+20(y-2007)$

and this way we can find the number of laptos at the end of 2017:

$y=2017$

and

$l=31+20(y-2007)$

$l=31+20(2017-2007)\\l=31+20(10)\\l=31+200\\l=231$

You worked from 8:30am - 2:15pm with a 12 hour lunch break. How long did you work?

alexandr402 [8]

5.75 if you don’t count the lunch break because I don’t think a lunch break can be twelve hours because it would’nt even be a shift

Kite WXYZ is graphed on a coordinate plane. What is the approximate perimeter of the kite? Round to the nearest tenth. 10.6 unit

Archy [21]

<u>Answer-</u>

<em>Perimeter of the kite is </em><em>16.2 units</em>

<u>Solution-</u>

As WXYZ is a kite, so two disjoint pairs of consecutive sides are congruent, i.e WX=XY and WZ=ZY

So, perimeter of the kite WXYZ is,

$=2(\overline{WX}+\overline{WZ})$

And

$\overline{WX}=\sqrt{(1-3)^2+(1-4)^2}=\sqrt{(-2)^2+(-3)^2}=\sqrt{4+9}=\sqrt{13}$

$\overline{WZ}=\sqrt{(1-3)^2+(1+3)^2}=\sqrt{(-2)^2+(4)^2}=\sqrt{4+16}=\sqrt{20}$

So, perimeter will be,

$P=2(\sqrt{13}+\sqrt{20})=16.15\approx 16.2\ units$
