Answer:
amount: rs 400
percentage: 12.5%
Step-by-step explanation:
Before VAT: rs 3200
After VAT: rs 3600
VAT = 3600 - 3200 = 400
VAT = rs 400
percent = part/whole * 100%
percent = 400/3200 * 100%
percent = 12.5%
Let the length be x.
Length = x
Width = x + 7
Area = Length x Width = x (x + 7)
x(x + 7) = 170
x² + 7x - 170 = 0
Answer: x² + 7x - 170 = 0
Get 9 to the other side by subtracting 9 on both sides which leaves you with x= -2 because 7-9= -2
