The correct answer is 98.
u + xy = 18 + (10)(8) = 18 + 80 = 98.
To evaluate the expression u + xy, where u = 18, x = 10, and y = 8, follow these steps:
1. Replace the variables u, x, and y with their respective values:
u + xy = 18 + (10 * 8)
2. Perform the multiplication first:
u + xy = 18 + 80
3. Finally, perform the addition:
u + xy = 98
Therefore, the answer is 98.
To evaluate the expression u + xy, we substitute the given values of u, x, and y into the expression.
Given:
u = 18
x = 10
y = 8
Substituting these values into the expression, we have:
u + xy = 18 + 10 * 8
Now, we need to follow the order of operations (also known as PEMDAS) to simplify the expression. Multiply before addition.
Multiplying:
10 * 8 = 80
Now, adding:
18 + 80 = 98
Therefore, u + xy equals 98.
The correct answer is: 98
