5x5 - x - 5
5x5 is 25 5x5 is 25 25x25 is 625
2x2x2 = 8 and 5x5 = 25 8+25 = 33
-6x3 + 4x7 - 0.8x2 + x4 - 5x5 = 4x7 - 5x5 + x4 - 6x3 - 0.8x2 = x2 (4x5 - 5x3 + x2 - 6x - 0.8)

There are 100 centimetres in one metre. Therefore, 494 centimetres is equal to 494/100 = 4.94 metres.

-5 x 5 = -25
25x1 or 5x5
5x5=144
5x(x^4+7x+4)
2x2=4 x2=8 x2=16 x2 = 32 and 5x5 = 25 so no, I guess not.
