How do you factor this 2x2 plus 13x plus 15?
2x2+13x+15 = (2x+3)(x+5)
7x-5 plus 2x equals 3-4x plus 12?
7x-5+2x=3-4x+12 7x+2x-5=3+12-4x 9x-5=15-4x 9x+4x-5=15-4x+4x 13x-5=15 13x-5+5=15+5 13x=20 13x/13=20/13 x=20/13
How do you factor 2x to the second power plus 13x plus 15?
2x^2 + 13x + 15 factored means that the two numbers must multiply to the constant (15) and add to equal the coefficient on the X (13). So it becomes: (2x + 3) (x + 5). If expanded, 2x*5 = 10x and 3 * x = 3x which add to 13x. And 5 * 3 = 15
What 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 plus 15 equals to?
It equals 285
What is the order pair 2x plus 5y equals 2 and -3x-y equals -3?
2x + 5y = 2 ..... Eq.1-3x - y = -3 ..... Eq.2 .... we can write it in another form y = 3 - 3xPut the value of y in Eq.1 the result will be :2x + 5(3 - 3x) = 22x + 15 - 15x = 22x - 15x + 15 = 2-13x + 15 = 2-13x = 2 - 15-13x = -13x = -13/-13 ......... X = 1to find Y, put the value of X in Eq.2y = 3 - 3xy = 3 - 3(1)y = 3 - 3 .......... Y = Zero
