we will be investigating applications
of so
through factoring and three depart attic formula
southern looking i think you'd area have a bhakti njan garden shed that has a
forty year yet forty meter squeaker
and asked if i need to mentions of the shed if the link is two leaders left in
the winter
what we're going to look to do it is using idea of systems of equations to
set up two-week lesions with to variables
mayberry levels will say alley puzzling interview equals with
and i know i have been area equation
you yet you close linked hands with soap fourteen disney area
late tense the way it
and it says that all linked is two meters less than the width so
link equals w minus two
here is my first
and my second he creation into variables
we're now going to take a cheek lesions
he and you substitution to itself
so we know that linked teams with equals forty eight
and link because with mains team
that will get something to you the contrary creation for google inc
giving us the new recreation of w my next to tang's w equals forty eight
to solve this using your and receiving something bad factoring
we need to distribute
w
now we have w squared minus two w equals forty eight
we have to set this equal to zero
sir dudley squared minus two w minus phony because zero
all right
now we consult if debu minus eight
tang's w cusick seek was derailed in reno that debbie both eight w equals a
negative six
let's think about our answers
temperamentally being naked it
we calm at the start the problem was about
of directing your guardian shack
and measurement cannot be negative
they are four debu cannot equal
and negative six
even this real-world problem
so we would say that the with equals eight meters handy recognizing if the
with
e militaries
arming than is eight minuscule or sixty tears
i don't want to think that all negative answers will be eliminated some let's
look at
consecutive integers
where into winter nights the temperature dropped below zero degrees fahrenheit
the two countries were consecutive negative images
and consecutive means
the products were product to sponsor cation of the country's was one hundred
and seventy two
so what are the two temperatures
will be could say that *** equals the smaller interpreter
and it acts as the smaller and richard then who won the consecutive imager
larger is *** plus one
we can't think of
two consecutive integers
in four
began if we said acts
equals thirty
then we have to and one more to get to four
this is where we came up with a cartoon variables
so the product of two degrees was one hundred and seventy two suite one
hundred seventy two equals
s one of the integers
tens acts plus one the other integer
distributing *** and have one seventy two equals ask layered plus acts
have to step back equal to the overall
bien factor
zero equals asp of seventeen
times estimated sixteen
that means that ask the smaller temperature is a negative seventeen or s
equal sixteen
however because we were looking at degrees below zero
we want ax people to you and negative seventeen
as our cancer
so if ask the smaller temperatures negative seventeen
the negative seventeen plots wine
or negative sixteen
is the other temperature
so
the two temperatures
naked seventeen decrees and negative sixteen
decrees
and if we multiply negative seventeen
times negative sixteen as we said we're taking the project we do indeed
one hundred seventy two
in this
question that we have a gardening measuring twelve meter sprints excluding
where twelve meters
and are sixteen wilderness
we're installing a pedestrian pathway all around it
increasing the total ineptitude underneath eighty-five square meters
kathleen uniform and think
and so
we are adding acs
born leaders
but sarin
uh...
contractual job location
this means that article link on six team leaders
we are planning to act
fluid acts
stairs one and the second acts this kid ruffling equals two acts plus sixteen
welcome in the basement added
in the packet ended
our tax standard sleek and to acts being added to that
we can recall that area is link
times with
for a rectangle
and so are linked of two x plus sixteen is the multiplied by a with two acts
plus twelve
and i said that he quits working area to hunting eighty five
hindustan anne
distributed does binomial czar foiled in and banner pay subtracted it to
eighty-five to set this equal to see a problem
amato forex clarion costs fifty six packs minus ninety three
and not sure come on a tight back to you can indiana not sure if it's even travel
incentives an instance where i would like to use the park at it
***
using a quadratic formula
you can see that acts equals the opposite being negative t six plus or
minus be squared
minus four tens intends to
that is the matter much numbers to work with but unique and
we end up with the negative fifty six plus a minus sixty eight
dividing bank
and when defining deposit and the negative versions of both of these
cancers
i found that act sequels and negative fifteen point five
or acts equals one point five
again in this real world situation we know that the with can not
equal a negative let's ask
we cannot have and negative
measurement of this parkway
so
the pathway cannot people a negative fifteen point five meters
so the pathway
or acts
equals one point five leaders
