Final answer:
The value of xy + yz + zx when x=4, y=3, and z=2 is 26, after performing the calculations: xy = 12, yz = 6, and zx = 8, and then summing them up.
Step-by-step explanation:
To find the value of xy + yz + zx when x=4, y=3, and z=2, we perform the following calculations:
- First, multiply x and y to get xy: 4 * 3 = 12.
- Next, multiply y and z to get yz: 3 * 2 = 6.
- Then, multiply z and x to get zx: 2 * 4 = 8.
- Finally, add these values together: 12 + 6 + 8 = 26.
Therefore, the value of xy + yz + zx when x=4, y=3, and z=2 is 26.
