How do u find the perimeter of a rectangle

dusk plinth Oct 23, 2023, 5:37 PM

#

wait i’ve done like half of it but i’m stuck on one thing

#

for shape a i’ve got 4x+6y=39 and i need to find y

tranquil osprey Oct 23, 2023, 5:37 PM

#

What’s your perimeter for shape B

dusk plinth Oct 23, 2023, 5:38 PM

#

4x+5y=34.5

tranquil osprey Oct 23, 2023, 5:38 PM

#

So now u have 2 equations do u know what to do to find x and y

dusk plinth Oct 23, 2023, 5:39 PM

#

for shape a do we have to -6y on both sides ?

tranquil osprey Oct 23, 2023, 5:39 PM

#

There’s an easier thing to do to eliminate x

dusk plinth Oct 23, 2023, 5:39 PM

#

if it was 6 instead of 6y i would know how to work it out it’s confusing me

#

tranquil osprey There’s an easier thing to do to eliminate x

ahhh

#

this is confusing

tranquil osprey Oct 23, 2023, 5:41 PM

#

Have u learnt how to solve simultaneous equations

dusk plinth Oct 23, 2023, 5:41 PM

#

no, my teacher gave it as hw one time but we never covered it

tranquil osprey Oct 23, 2023, 5:41 PM

#

Oh alr

#

Might be useful to watch a vid on solving linear simultaneous eqs

dusk plinth Oct 23, 2023, 5:42 PM

#

yeah

#

i will thank u

tranquil osprey Oct 23, 2023, 5:42 PM

#

You basically want to eliminate one of the variables so that u can solve for the other one
