We know that x = 5 and y = 12, so we can use the original equation to determine that z = 13 We can plug in all the values that we now know 2(13) dz dt = 2(5)2 2(12)3 dz dt = 46 13 Note that z could also equal −13, but I am assuming that the physical restrictions behind this problem would not allow such an answer, indicating the origin and coordinates x and y Then indicate the area of xy <•2(x3)=2xλ (12) •2(y1)=2yλ (13) •2(z1)=2zλ (14) •x 2y z2=4 (15) •The simplest way to solve these equations is to solve for x, y, and z in terms of λ from (12), (13), and (14), and then substitute these values into (15)
