I’m sorry I don’t get that whole situation
School to mall - 16 miles
mall to library - 30 miles
16²+30²=X²
256+900=X²
X²=1156
X=34
16+30=46
hypotenuse = 34
46-34=12
So Mike travel 12 miles more.
9 is the answer negatives cancel out creating positve
I think its B but ima have to check again and get back to you
Hi there
9a + 3(8-2a)
9a + 24 - 6a
(9a -6a) +24
3x + 24
I hope that's help !
