The missing value for
is 
Explanation:
It is given that the equation for the table is 
The table has 2 column with 5 rows.
Thus, we have,
x y
-2 10
-1 ---
0 2
1 -2
2 -6
We need to determine the value of y when 
The value of y can be determined by substituting
in the equation 
Thus, we have,

Multiplying the term within the bracket, we have,

Adding the terms, we have,

Thus, the value of y when
is 6.
Hence, the missing value for
is 
Answer:
There's two ways to solve this.
Step-by-step explanation:
First way:
Let's divide the width and length by 2.3.
46÷2.3=20
69÷2.3=30
20×30
600 ft²
Second Way:
Let's find the area of the actual room.
46×69
3,174 ft²
Let's find the scale drawing squared.
2.3²=5.29
3,174÷5.29
600 ft²
