Answer:

# 8a - 9 #

Explanation:

ohai
I'll explain as to how

First of all, following order of operations, open the brackets first

# 4(2a + 2) - 17 #
# 8a + 8 - 17 #

Now, as you see here, we multiplied 4 with both values in the brackets, as we're supposed to do since we opened the brackets, and the equation, less simplified looked like

# 4*(2a + 2) - 17#

Thus, now that we opened the brackets, lets see the like terms over here

# 8a + 8 - 17#
The like terms over here are 8 and -17, and 8a, by itself since it's the only one with a variable along with it

So now, since we have the like terms together, lets simplify more
How to? Of course, by calculating 8 - 17

#8a - 9#

Aaaaand..... that's our answer
