Derivative with respect to x: 
Derivative with respect to y: 
Derivative with respect to z: 
Step-by-step explanation:
We can calculate three derivatives for this function: the derivative with respect to x, the derivative with respect to y, and the derivative with respect to z.
We start with the derivative with respect to x:

Then we calculate the derivative with respect to y:

Finally, we calculate the derivative with respect to z:

2700 bc in everminutes he would run 920
(x-3)2+(y-4)2=24
2x-6+2y=24
2x-14+2y=24
2x=24+14-2y
2x=38-2y
x=19-y
The answer is B) <span>(q - 2)(2p - 5r)
</span>2pq - 5qr + 10r - 4p = 2pq - 4p - 5qr + 10r
= 2pq - 4p - (5qr - 10r)
= 2p(q - 2) - 5r(q - 2)
= (q - 2)(2p - 5r)
