(5x+4)(9x+9) FOIL First (5x*9x=45x**2) Outside (5x*9=45x) Inside (4*9x=36x) Last (4*9=36) 45x**2+45x+36x+36 45x**2+81x+36 9(5x**2+9x+4x)
How much is 9x equals 4x plus 45?
9x = 4x + 45 5x = 45x = 9
What is the slope of any line parallel to the line formed by the equation 45x plus 9y equals 36?
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
What is 3 over 5 x equals nine?
(3/5x) = 9......we cross multiply 9 by 5x 3 = 9(5x) 3 = 45x........dividing across by 45 3/45 = x x = 1/15
What is the factorization of this trinomial 3x3 - 24x2 plus 45x?
3x3 - 24x2 + 45x = 3x(x2 - 8x + 15) = 3x(x2 - 3x - 5x + 15) = 3x[ x(x - 3) - 5(x - 3) ] = 3x(x - 5)(x - 3)
What is the trinomial for 5x plus 4 9x plus 9?
(5x+4)(9x+9) FOIL First (5x*9x=45x**2) Outside (5x*9=45x) Inside (4*9x=36x) Last (4*9=36) 45x**2+45x+36x+36 45x**2+81x+36 9(5x**2+9x+4x)
How would you simplify the expression 9(5x)?
9(5x) = 45x simplified
What is the GCF of 45x squared and 40x squared?
5x squared
If an equilateral nonagon has one side of 5x-3 what is its perimeter?

How do you factor 5x4 plus 20x3plus 45x equals?
5x is a common factor of all terms:- 5x(x3+4x2+9)
How do you solve x over 2 minus 5x over 6 1 over 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
How much is 9x equals 4x plus 45?
9x = 4x + 45 5x = 45x = 9
What is the slope of any line parallel to the line formed by the equation 45x plus 9y equals 36?
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
What is 3 over 5 x equals nine?
(3/5x) = 9......we cross multiply 9 by 5x 3 = 9(5x) 3 = 45x........dividing across by 45 3/45 = x x = 1/15
