15 x 30 x 15 feet holds 50,493.5 gallons.
If x>1 then the gcf is 15x. If x<1 then the gcf is 15.
15x2 - 30x -720 = 15(x - 8)(x + 6).
The GCF of 30 x^2 and 45x is 15x. The GCF of 30 and 45 is 15, and the GCF of x squared and x is x.
25x2+30x+9 25*9=225 15*15=225 15+15=3025x2+15x+15x+9[5*5xx 3*5x] [3*5x 3*3]5x(5x+3)+3(5x+3)(5x+3)(5x+3)Answer: (5x+3)2
15x2 + 2x - 56 = 15x2 + 30x - 28x - 56 = 15x(x + 2) - 28(x + 2) = (15x - 28)(x + 2)
When X = 4, 15X = 15 * X = 15 * 4 = 60
2x2 - 30x - 152 = 0 simplify x2 - 15x - 76 = 0 since -76 = -19 x 4 and -19 + 4 = -15, we have (x + 4)(x - 19) = 0 x + 4 = 0 or x - 19 = 0 x = -4 or x = 19
15x = 45 Solve for x by dividing both sides by 15. 15/15 x = 45/15 Simplify. x = 3
15x
15x
It is 15x.
The product of 15 and x is 15x. If you then want to substitute a numerical value for x to evaluate the expression of 15x when x equals that number then just multiply. For example, if x = 3, then 15x = 15(3) = 45 if x = 10, then 15x = 15(10) = 150 Good luck! :-)
