What is 10 plus 9 plus 8 plus 7 plus 6 plus 5 plus 4 plus 3 plus 2 plus 1 plus 0?
10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 + 0 = 55
What is 10 plus 9 plus 8 plus 7 plus 6 plus 5 plus 4 plus 3 plus 2 plus 1 plus 0 equals?
10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 + 0 = 55
How do you solve 20x2 plus 27x plus 9 equals 0?
20x^2 + 27x + 9 = 0 20x^2 + 15x +12x + 9 = 0 5x(4x + 3) + 3(4x + 3) = 0 (5x + 3)(4x + 3) = 0 So either (5x + 3) = 0 which yields x = -3/5 or (4x + 3) = 0 which yields x = -3/4
What is x2 plus 6x plus 9 equals x plus 3?
x2+6x+9 = x+3 x2+6x-x+9-3 = 0 x2+5x+6 = 0 Solve by factoring or with the help of the quadratic equation formula: (x+3)(x+2) = 0 Therefore: x = -3 or x = -2
What is 0 plus -3 plus -6?

What is 1 plus 0 plus 3 plus 4 plus 1 plus 0?
9
What is -9 plus 3 plus 2?
The answer is -9+3+2 = -4
X2 plus 7x equals - 2x2 plus 6?
x2 + 7x = -2X2+6 3x2 + 7x -6 = 0 (3x-2)(x+3) = 0 Either 3x-2=0 or x+3=0 Either x=2/3 or x=-3 Plug the numbers into the original equation to check. (2/3)2 + 7(2/3) = -2(2/3)2 +6 4/9 + 14/3 = -8/9 + 6 4/9 + 42/9 + 8/9 - 54/9 = 0 0=0 That one checks out. Let's try the second one. (-3)2 + 7(-3) = -2(-3)2 + 6 9 -21 = -18 + 6 9 -21 +18 -6 = 0 0=0 The second one checks out also; so both answers are good. Answer: x = 2/3 or x = -3
What is 9 plus 9 plus 9 plus 9 plus 9 plus 9 plus plus 6 plus 6 plus 6 plus 6 plus 2 plus 2 plus 23 plus 3 plus 3 plus 4 plus 4 plus 4?
9 + 9 + 9 + 9 + 9 + 9 + 6 + 6 + 6 + 6 + 2 + 2 + 23 + 3 + 3 + 4 + 4 + 4 = 123
