Given parameters:
Total length of curtains bought = 20m
She used 8m for the living room
She used 7m for the dining room
unknown:
Quantity used for the kitchen = ?
Solution:
Quantity used for the kitchen = Total length - (living room + dining room)
Input the parameters given solve;
Quantity used for the kitchen = 20 - (8 + 7) = 5m
The length of curtain used for the kitchen is 5m
None of these choices are correct
The down side of the shape is unknown and cannot be found, therefore you cannot find the perimeter of the shape.

Pls help me in homework
Remark
Remove the brackets. Then solve as a normal inequality.
Solution
4(x - 3) - 2(x - 1) > 0
4x - 12 - 2x + 2 > 0 Combine like terms on the left
4x - 2x - 12 + 2 > 0
2x - 10 > 0 Add 10 to both sides
2x > 10 Divide by 2
x > 10/2
x > 5
Answer: B
Discussion
C and D are both true but these questions always assume that you are going to pick the lowest value that will allow the inequality to be true. x> 7 and x>14 will be included in x>5
0.30 is the same as 3/10 so then you would add 3/10 and 4/10 which equals 7/10 which then gives you with 3/10 ice cream left
