X=-8.5
u would solve by isolating x
2 (n+1) + n² + 4 (n-3)
= 2n + 2 + n² + 4n - 12 ...expand by using distributive property
= n² + 6n - 10 ...combine like terms
hope it helps

Hi there!
First, let's round 8 9/10:
Since 9/10 is about 1, 8 9/10 is about 9
Now, let's round 1 4/5:
Since 4/5 is about 1 as well, 1 4/5 is about 2
9 * 2 = 18
So, the approximate answer is 18.
Hope this helps!
