To simplify the expression 5(14−2)22, we first calculate the value inside the parentheses: 14 - 2 = 12. Then we multiply this result by 5: 5 * 12 = 60.
Therefore, the simplified form of the expression is 60.
Therefore, the simplified form of the expression is 60.

To evaluate u + xy, we substitute the given values of u, x, and y into the expression:
u + xy = 18 + (10)(8) = 18 + 80 = 98.
Therefore, the value of u + xy is 98.
u + xy = 18 + (10)(8) = 18 + 80 = 98.
Therefore, the value of u + xy is 98.
