Answer:Alkanes: CnH2n+2
n=8 --> C8H18. So it is 18 atoms
Step-by-step explanation:
-7x-3x= -10x
-10x+2=-8x-8
-10x+8x+2=-8
-2x+2= -8
-2x = -8 + 2
-2x= -6
X= -6/-2
X= 3
Answer:
1
Step-by-step explanation:
(3x + 4)(px + q) = 12x^2 + ax - 20
3px^2 + 3qx + 4px + 4q = 12x^2 + ax - 20
3px^2 = 12x^2
p = 4
4q = -20
q = -5
px + q = 4x - 5
(3x + 4)(4x - 5) =
= 12x^2 - 15x + 16x - 20
= 12x^2 + x - 20
= 12x^2 + ax - 20
ax = x
a = 1
