Just did this one.
The perimeter is the sum of the sides.
n + (3n - 4) + (3n - 5) = 33
7n - 9 = 33
7n = 42
n = 6
3n-4=18-4=14
3n-5=13
Check: 6+14+13=33, good

Answer:
Slope is m=0
Step-by-step explanation:
The slope of any line that is perpendicular to the y-axis is zero.
The reason is that any line that is perpendicular to the y-axis is also parallel to the x-axis and the slope of the x-axis is zero.
The equation of any line perpendicular to the y-axis is and passes through (a,b) is y=b.
The given point is (-5,-3) hence the required equation is
Answer: 90°

Answer:
264 naira
Step-by-step explanation:
Given that:
Amount earned per year = 2460
Rate of interest paid : 10k per naira earned
Tax paid by messenger per year :

10k = (100/10) = 0.1 naira
Hence 0.1 naira is paid as tax on every naira earned
Total amount paid on 2640 Naira :
Amount paid per naira * total amount earned
(0.1 * 2640) = 264 naira
