After dividing & simplifying you will get u= 5/3.
The decimal is 0.6 to find the decimal form you take 9÷15 = 0.6
A=LW
A divided by W= L divided by W (cancels out)
Answer: A/W = L
Hope this helps! Can I get brainliest? lol
Divide both sides by -3, and replace
with
. Then

Factorize the quadratic in
to get

which in turn means

But
for all real
, so we can ignore the first solution. This leaves us with

If we allow for any complex solution, then we can continue with the solution we ignored:
