Question

A rectangular pool has a length that is 13 meters longer than its width. Its perimeter is 74 meters. What is the width of this pool?

Answer 1

Set up your equations
length is 13 plus width

what would the equation be like?
set length as l, width is w

Answer 2

um...................
13l + w = ?
e.e

Answer 3

haha idek xd

Answer 4

e.e
length equals 13 plus width
put that in letters and symbols._.

Answer 5

eh? l = 13 + w?

Answer 6

yep
and then we have
perimeter equals 74, so 2l+2w=74

So now, we these two equations, solve for w

Answer 7

2l + 2w = 74
13 + w = l

don't I multiply the second equation by -1 since I have 2 posi-
wait are we even eliminating??

Answer 8

omg- im sooo lost ;c

Answer 9

l=13+w
2l+2w=74

2(13+w) + 2w=74

Answer 10

?????

Answer 11

You substitute l=13+w into the equation of 2l +2w=74

Answer 12

Wait..
26w + 2w = 74??

was this correct ^ like the equation after you distribute?

Answer 21

sniff

Answer 22

acklvklghltyimkl7iluo

Answer 23

2(13+w) + 2w=74
a(b+c) = ab+ac
distribute the parenthesis again._.

Answer 24

okiee >.>

Answer 25

ohhh 26w + 2w.. +2w = 74?????

Answer 26

yep
and solve for w

Answer 27

add all them together- 30w = 74
74/30 = ?

Answer 28

IDKKKK

Answer 29

It's alr late snow ._.

Answer 30

26+4w=74
4x=48
x=12
