2*(8*5 + 5*3 + 3*8) = 2*(40 + 15 + 24) = 2*79 = 158 m2
-3m = 5m+8 -3m-5m = 8 -8m = 8 m = -1
To solve the equation 5m + 3 = 3m + 9, you need to isolate the variable m. Start by subtracting 3m from both sides to get 2m + 3 = 9. Then, subtract 3 from both sides to get 2m = 6. Finally, divide by 2 to find m = 3.
5m = 2m - 153m = -15m = -15/3m = -5
40 cubic meters
-15m but -15 metres doesnt exist
3m by 5m by 3m
2*(3*5 + 5*8 + 8*3) m2 = 2*(15 + 40 + 24) m2 = 2*79 m2 = 158 m2
5*4*3 60?
Assuming this is a rectangular prism, the surface area would be 2LW+2LH+2HW. So the surface area for this object would be: 2*3*5+2*3*8+2*8*5=30+48+80=158 square meters.
-7m - 3m + 5m = -5m
To find the possible whole number dimensions of a rectangular prism with a volume of 30m^3, we need to factorize 30 into pairs of whole numbers. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. By pairing these factors, we can determine the possible dimensions of the rectangular prism. The possible whole number dimensions for a rectangular prism with a volume of 30m^3 are: 1m x 1m x 30m, 1m x 2m x 15m, 1m x 3m x 10m, 1m x 5m x 6m, 2m x 3m x 5m.

The volume of a rectangular prism can be calculated using the formula: volume = length × width × height. For the given dimensions of 8m, 4m, and 5m, the volume is 8m × 4m × 5m = 160 cubic meters. Therefore, the volume of the rectangular prism is 160 m³.
-3m = 5m+8 -3m-5m = 8 -8m = 8 m = -1
To solve the equation 5m + 3 = 3m + 9, you need to isolate the variable m. Start by subtracting 3m from both sides to get 2m + 3 = 9. Then, subtract 3 from both sides to get 2m = 6. Finally, divide by 2 to find m = 3.
5m-3x+3m+2x 2m-x
Every one of them could be a side of a rectangle. It is not possible to give an answer in respect of an unspecified rectangular object. however, i feel the question is incorrect as it should be sides of the triangle and according to it 3rd is the answer as 3+5<9 :)
