Step-by-step explanation:
Step-by-step explanation:
2×9n=18n
2×-6=-12
52-12+18n= 38 +18n
2×7n=14n
8×2=16
14n+16
38+18n=14n+16
subtract 14n from 14n and 18n
38+4n=16
subtract 38 from 38 and 16
4n=-22
divide each side by 4
n= -5.5

<h3>Length of table is 2.7 meter and width of table is 1.2 meter</h3>
<em><u>Solution:</u></em>
Let "x" be the length of table
Let "y" be the width of table
four times the length equals nine times the width
Therefore,
4x = 9y
The perimeter of a pool table is about 7.8m
Perimeter = 7.8 meter
2(length + width) = 7.8
Therefore,
Thus length of table is 2.7 meter and width of table is 1.2 meter
