8 because x = 399 and 17*23 = 391

More generally, x = 399 + 299*n where n is ANY integer.

46 is the 23% of 200.23 x = 4623 x = 4600x = 200
I take it you referring to Avogadro's number which is related to the mole (see link), the answer is a very long time. It works out to 19,076,228 years! Solution: Avogadro's number, which is 6.02 times 10 raised to the 23 power is divided by 86,400, the number of seconds in a day, which equals 6,967,592,592, which is then divided by the average number of days in a year, 365.25, which in turn yields 19,076,228.
Assuming that by expressing that equation as a question you're looking to solve for x: x2 - 4x - 29 = -10 x2 - 4x + 4 = 23 (x - 2)2 = 23 x - 2 = ± √23 x = 2 ± √23
This browser is pathetic for mathematical answers but here's the best that I can do:Let u = 23x therefore du/dx = 23let dv/dx = e^(2x) therefore v = 1/2*e^(2x)then, integrating by parts,I = I(u*dv/dx) dx = u*v - I(du/dx*v) dx= 23x*(1/2)*e^(2x) - I(23*(1/2)*e^(2x) dx= 23/2*xe^(2x) - 23/2*I(e^(2x)) dx= 23/2*xe^(2x) - 23/2*(1/2)*e^(2x)= 23/2*xe^(2x) - 23/4*e^(2x)or 23/4*e^(2x)*(2x - 1)
