X2 - 16X + 15 = 0
(X - 1)(X - 15) = 0
So X -1 = 0 or X - 15 = 0
ie X = 1 or X = 15
Yes that is correct
If 40 plus x equals 25 then x is equal to -15.
15
7+x=15 x=8
8x = 2x + 15 6x = 15 x = 15/6 = 2.5
x+15=16x=16-15x=1
If: 16x-15-6x = 13 Then: 10x = 28 And: x = 2.8.
15x2+16x-15 = (3x+5)(5x-3) when factored
The given expressions can be simplified to: 16x-10
-15
(2x - 5)(2x - 3)
(5x - 3)(3x + 5)
It will be: 6x2 +8x -15
It equals 285
45
1-16x speed = -15
3a + 15 = 4a Subtract 3a from both sides 15 = a So a is 15.
