Answer and step-by-step explanation:
5-2(n+2)
we learn that: a*(b-c) = a*b - a*c so in this case:
5-2(n+2)
= 5 - 2n +(-4)
= 5 - 2n - 4
= 5 - 4 -2n
= 1-2n
When you compare 1-2n and 4+n
If n is a positive number (>0), 1-2n < 4+n
For example if n =3
1-6 compare with 4+3
-5 < 7
If n is a negative number (<0), 1-2n > 4+n
For example if n = -3
1 - 2*(-3) compare with 4 + (-3)
= 7 compare with 1
If n is 0 (n=0), 1-2n < 4+n
1-0 compare with 4+0
1 < 4
Hope this help you :3
