Factor x² plus 13x plus 40?
x2 + 13x + 40 = x2 + 5x + 8x + 40 = x(x + 5) + 8(x + 5) = (x + 8)(x + 5)
If 5 x-3 equals 2-8 x then x equals?
5x-3=2-8x 5x-3+3=2-8x+3 5x=5-8x 5x+8x=5-8x+8x 13x=5 x=5/13
7 plus 8x-5 equals 8x plus 7-5x?
7+8x-5 = 8x+7-5x Subtract 7 from both sides: 8x-5 = 8x-5x Subtract 8x from both sides: -5 = -5x Divide both sides by -5: x = 1 So the equation implies x = 1
How do you factorise 8x plus 20?
8x + 20 = 4 (2x + 5)
Factor x2 plus 8x plus 15?
x2 + 8x + 15 = (x + 3)(x + 5)
Factor x² plus 13x plus 40?
x2 + 13x + 40 = x2 + 5x + 8x + 40 = x(x + 5) + 8(x + 5) = (x + 8)(x + 5)
What is -8x plus 4 equals -13x -1?
-8x + 4 = -13x - 1 Add '13x' to both sides Hence 5x + 4 = -1 Subtract '4' from both sides 5x = -5 Divide both sides by '5' x = -1
What is 2 plus 3w-13x plus 5?

What is x if 13x plus 15 equals 11x-5?
13x + 15 = 11x - 5 2x = -20 x = -10
Two numbers are in the ratio 5 to 8 If the sum of the numbers is 182 Find the numbers?
Let a : b = 5 : 8If the unit part is x, then a = 5x and b = 8x. So we have:5x + 8x = 18213x = 182 divide both sides by 13x = 14Then,a = 5xa = 5 x 14a = 70b = 8xb = 8 x 14b = 112
