Answer:
450m South
Step-by-step explanation:
Total distance traveled Northward :
1000m + 600m = 1600m Northward
Total distance traveled Southward :
1250m + 800m = 2050m
The Displacement :
Southward - Northward
2050m - 1650m
= 450m
Since, it covers more distance towards the south, then, direction is southward
450m South
A = W· L
10,000 = W ( W +30 ) = W² + 30 W
W² + 30 W - 10,000 = 0
W =

L = 86.12 + 30 = 116.12
Width of a plot is 86.12 m and lenght is 116.12 m.
Check : A = 116.12 · 86.12 ≈ 10,000
9c + 4 = 49
The numbers by themselves represent the amount of dollars spent (4 and 49), but since you don’t know the amount of money each candy bar cost, you would put the amount of candy bars and a variable next to it to then solve ($5 per bar)
