The simplified form of the expression is 60.
Answered by GPT 3.5
If u = 18, x = 10, and y = 8, then u + xy can be calculated as follows:

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

Therefore, the value of u + xy is 98.

To find the length of a side of the square field, we can take the square root of the area since all sides of a square are equal.

Taking the square root of 479 ft² gives us approximately 21.88. Since we need to round to the nearest foot, the approximate length of a side of the field would be 22 feet.

We round up to 22 rather than down to 21 because it is closer to the actual value of 21.88.

To simplify the expression (7+5)+4⋅13−2, we follow the order of operations: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

First, we simplify the expression within the parentheses:

(7 + 5) = 12

Now, the expression becomes:

12 + 4⋅13 - 2

Next, we perform the multiplication:

4⋅13 = 52

Now, the expression is:

12 + 52 - 2

Lastly, we perform the addition and subtraction:

12 + 52 = 64

64 - 2 = 62

Therefore, the simplified expression is 62.
