To factor the polynomial ( 125x^3 + 45x ), first, we can factor out the greatest common factor, which is ( 5x ). This gives us ( 5x(25x^2 + 9) ). The quadratic ( 25x^2 + 9 ) cannot be factored further using real numbers since it does not have real roots. Therefore, the complete factorization is ( 5x(25x^2 + 9) ).
The slope of any line parallel to the line described is -5. Solution: 45x+9y=36. Solve for y. 9y=36-45x. y= -5x+4 m=-5
(3/5x) = 9......we cross multiply 9 by 5x 3 = 9(5x) 3 = 45x........dividing across by 45 3/45 = x x = 1/15

5x is a common factor of all terms:- 5x(x3+4x2+9)
x/2 - 5x/(61/9) = x/2 - 5x(9/61) = x/2 - 45x/61 the least common denominator is 122 = [(x)(61)]/122 - [(45x)(2)]/122] = (61x - 45x)/122 = 16x/122 = (16x ÷ 2)/(122 ÷ 2) = 8x/61
9x = 4x + 45 5x = 45x = 9
The magnification of a microscope is determined by multiplying the magnification of the objective lens by the magnification of the eyepiece. In this case, if you have a 45x objective lens and a total magnification of 225x, the eyepiece magnification would be 225x divided by 45x, which equals 5x. Therefore, the power of the eyepiece would be 5x.
To factor the polynomial ( 125x^3 + 45x ), first, we can factor out the greatest common factor, which is ( 5x ). This gives us ( 5x(25x^2 + 9) ). The quadratic ( 25x^2 + 9 ) cannot be factored further using real numbers since it does not have real roots. Therefore, the complete factorization is ( 5x(25x^2 + 9) ).
