What is the value of 9 (n+2) — 5n for n = 1/4? a. 3 b. 9 c. 10 d. 19

Sure! Let's go through this.
First, we can simply plug 1/4 in for n
9(1/4+2)-5(1/4)
Then, we can use the distributive property and simplify.
9/4+18-5/4
We can combine the 9/4 and -5/4 to get
4/4+18
We notice 4/4=1, so we have
1+18
Which gets us our final answer of 19.
Hope this helps!
