Answer (2)

Calculate 100 − 2 x for each x value.
Calculate A = x ( 100 − 2 x ) for each x value.
Fill in the table with the calculated values.
The completed table values for A are 0 , 450 , 800 , 1050 , 1200 , 1250 , 1200 , 1050 , 800 , 450 , 0 ​ .

Explanation

Understanding the Problem We are given the formula A = x ( 100 − 2 x ) and asked to complete the table of values for different values of x . The table has three rows: the first row contains the values of x , the second row contains the values of ( 100 − 2 x ) , and the third row contains the values of A = x ( 100 − 2 x ) .

Calculations for x = 5 Let's calculate the values of ( 100 − 2 x ) and A for each given value of x .

Calculations for x = 10 When x = 5 , we have: 100 − 2 x = 100 − 2 ( 5 ) = 100 − 10 = 90 A = x ( 100 − 2 x ) = 5 ( 90 ) = 450

Calculations for x = 15 When x = 10 , we have: 100 − 2 x = 100 − 2 ( 10 ) = 100 − 20 = 80 A = x ( 100 − 2 x ) = 10 ( 80 ) = 800

Calculations for x = 20 When x = 15 , we have: 100 − 2 x = 100 − 2 ( 15 ) = 100 − 30 = 70 A = x ( 100 − 2 x ) = 15 ( 70 ) = 1050

Calculations for x = 25 When x = 20 , we have: 100 − 2 x = 100 − 2 ( 20 ) = 100 − 40 = 60 A = x ( 100 − 2 x ) = 20 ( 60 ) = 1200

Calculations for x = 30 When x = 25 , we have: 100 − 2 x = 100 − 2 ( 25 ) = 100 − 50 = 50 A = x ( 100 − 2 x ) = 25 ( 50 ) = 1250

Calculations for x = 35 When x = 30 , we have: 100 − 2 x = 100 − 2 ( 30 ) = 100 − 60 = 40 A = x ( 100 − 2 x ) = 30 ( 40 ) = 1200

Calculations for x = 40 When x = 35 , we have: 100 − 2 x = 100 − 2 ( 35 ) = 100 − 70 = 30 A = x ( 100 − 2 x ) = 35 ( 30 ) = 1050

Calculations for x = 45 When x = 40 , we have: 100 − 2 x = 100 − 2 ( 40 ) = 100 − 80 = 20 A = x ( 100 − 2 x ) = 40 ( 20 ) = 800

Calculations for x = 50 When x = 45 , we have: 100 − 2 x = 100 − 2 ( 45 ) = 100 − 90 = 10 A = x ( 100 − 2 x ) = 45 ( 10 ) = 450

Final Calculations and Table Completion When x = 50 , we have: 100 − 2 x = 100 − 2 ( 50 ) = 100 − 100 = 0 A = x ( 100 − 2 x ) = 50 ( 0 ) = 0

Completed Table So, the completed table is:

Examples
This formula can be used to model the area of a rectangular garden with a fixed perimeter. For example, if you have 100 meters of fencing to enclose a garden, and you want to maximize the area, you can use this formula to determine the optimal dimensions. By varying the width 'x', you can calculate the corresponding length (100-2x) and the area A. This helps in practical applications like gardening, where optimizing space is important.

The table values for A are completed using the formula A = x ( 100 − 2 x ) . For each value of x , we calculated 100 − 2 x and then A accordingly. The completed table shows the relationship between x , ( 100 − 2 x ) , and A .
