Answer:
AB = 16 units
Step-by-step explanation:
Given the coordinate (-4, 9) and (-4, -7)
Using the formula for calculating the distance between two points
AB = √(x2-x1)²+(y2-y1)²
AB =√(-7-9)²+(-4+4)²
AB = √(-16)²+0²
AB = √16²
Hence the distance between Point A and Point B is 16 units
Answer: 16x + 4y= 80
16 (3) + 4 (8) = 80

The total price for 5 days
First, calculate the total for a day.
Open bracket
For 5 days, the total will be.
Total = days * sales of a day
