15m + 4n - 5m + 9n = 10m + 13n
5m-12n
15m because if its 5m BY 3m then the by is standing for the OF witch it a mathematical phrase for algebra and witch means to multiply the base by height. and the area is found by multiplying the sides together. so 5m multiplied by2m is 15m
-7m - 3m + 5m = -5m
Total distance travelled = 20m + 15m = 35m Total displacement travelled=20m - 15m =5m
75m2 if in a square is 8.66m by 8.66m, alternatively 15m by 5m is also 75m2
Fihd
5m-12n
5m = 2m - 153m = -15m = -15/3m = -5
5m + 7 - 2m - 1 = 3m + 6
5m+2n, n-3m, 7-3n (5m+2n)+(n-3m)+(7-3n)=2m+7
15m because if its 5m BY 3m then the by is standing for the OF witch it a mathematical phrase for algebra and witch means to multiply the base by height. and the area is found by multiplying the sides together. so 5m multiplied by2m is 15m
There are 4 terms
5m-5n+5m+5n When simplified: 10m
-15m but -15 metres doesnt exist
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
-7m - 3m + 5m = -5m
Total distance travelled = 20m + 15m = 35m Total displacement travelled=20m - 15m =5m
