Evaluate u + xy, if u = 18, x = 10, and y = 8.

A. 188

B. 36

C. 98

D. 224

There are lot of information's already given in the question. Based on these information's the answer can be easily deduced. The equation given in question is

u + xy = 18 + (10 * 8)

= 18 + 80

= 98

From the above deduction, we can conclude that the correct option among all the options that are given in the question is the third option or option "C".

If you would like to evaluate u + xy, you can do this using the following steps:

u = 18, x = 10, y = 8

u + xy = 18 + 10 * 8 = 18 + 80 = 98

The correct result would be C. 98.
