Let the width be x, then the length is x + 12.
Area = length x width = x(x + 12) = 589
Solving the quadratic equation, we have that
x = 19 feet
i.e. the width is 19 feet.
Answer:
a) 3
b) 12
c) 4
Step-by-step explanation:
a)
17 - 4x = 8 - x
9 = 3x
x = 3
b)
3x ÷ 4 = 9
3x = 36
x = 12
c)
5x + 6 × (x + 2) = 56
5x + 6x + 12 = 56
11x = 44
x = 4
Answer: B
Step-by-step explanation:
The function is Count.
There are many functions available on a database to do aggregated calculations. So they can be referred as aggregate functions. The aggregate functions available are:
- count: To get the the number of rows with a specified criteria.
- sum: To get the sum of values on the selected cells.
- max: To get the maximum value within a selected range of data.
- min: To get the minimum value within a selected range of data.
- avg: To get the average of the selected data.
As the field name referred here is 'lastname', the appropriate aggregate function would be count.

subtract the 2 to find the difference:
279.48 - 250.55 = 28.93
divide difference by actual amount:
28.93 / 279.48 = 0.1035
rounded to the nearest tenth = 10.4%
