Answer:

Step-by-step explanation:
Let the numbers be 
Such that:

Make z the subject

For their product to be maximum, we have:

Substitute
in 

Open bracket

Differentiate w.r.t x and y


Since the products are maximum, then 
For 

Factorize:

Split

Make y the subject

For 

---------------------------------------------------
Substitute y = 0


Factorize



---------------------------------------------------
Substitute 



Re-arrange


Factor x out

Divide through by x



Recall that: 


Take LCM


Recall that:


Take LCM


Hence, the numbers are:

Answer:
45
Step-by-step explanation:
Answer:
B = minus 15 is greater than 21 = as the line stops at 3^2 and shows 15 with shaded circle
It stops at -5^2 open circle and -5 x -5 = = 25
So if we use a value more than this -4.6 x -4.6 = 21
