We start with:
-10 = xy + z
When you want to solve for a certain variable, you generally follow pemdas in reverse, so subtract z from both sides first:
-10 - z = xy
And finally, divide both sides by y:
(-10 - z)/y = x
and there we go! sorry for the badly typed equations, I'm on my phone so there's only so much a can do :( hope I helped, and let me know if you have any questions!
Let the breadth be x
length=x+8
according to the question
area of the pool = l*b
105=x*x+8
if u solve this equation further u will get the answer

I’m not absolutely sure but I believe the answer is around 6
Answer:
f(x) = 488
Step-by-step explanation:
first you plug in 82 in for x then you multiply by 6 times 82 and you get 492 then you subtract 4 and you get 488
