D. -2n - 6 = 9
Step-by-step explanation:
The first step you have to do is the distributive property in the given equation. So, you multiply n and 3 by -2. The resulting equation is -2n - 6 = 9.
the answer is the last one
so the answer is d
10x²+2x-8=0
=>10x²+10x-8x-8=0
=>10x(x+1)-8(x+1)=0
=>(10x-8)(x+1)=0
=>2(5x-4)(x+1)=0
Option B
