84= 7(6+a)
84= 42 +7a
84-42= 42-42 +7a
42= 7a
42/7= 7a/7
6= a
-84= -6( p+6)
-84= -6p -36
-84+36= -6p -36+36
-48= -6p
-48/-6= -6p/-6
8 =p
Do Area = (base 1 + base2) × H
6, 2, -2 i could be wrong :/
The answer is 3 because since b=-5 you get -5 and add it to 14 giving you 9 and then you divide 9/3 which gives you 3. Hope this helps :)
