14x(x + 2)
If you mean: 14x = 129.5 then x = 129.5/14 = 9.25
x = 1.5 because -7x + 3 = -15/2 -14x + 6 = -15 (x2) -14x + 21 = 0 (+15) 21 = 14x (+14x) 3 = 2x (/7) 1.5 = x
The polynomial IS written in descending order.
98x
As written, that equals 325 - 14x which is in its simplest form.
14x+12y+7 This expression cannot be simplified any further.
(x-7)2
14x = 7y+28 -7y = -14x+28 Divide all terms by -7 to find the value of y: y = 2x-4 which is now in slope intercept form
-14x-7 = 35 -14x = 35+7 -14x = 42 x = -3
14x + 6 = 6 14x + 6 - 6 = 6 - 6 14x = 0 14x / 14 = 0 / 14 x = 0
-14x
if you mean (3/(2x-5))(21/(8x2-14x-15)) you would get (63/( (2x-5)(4x+3)(2x-5) ) simplified more would be 63/ ( (2x-5)2(4x+3) )
(x - 8)(x - 6)
-11
If: -14x = -98 Then: x = 7
