Answer:
Lisa bought 9 gallons of ice cream
Step-by-step explanation:
lets take "x" as the gallons of lemonade
if Lisa made purchases worth $34 that is what our equation will e equal to
ice cream:7.5 per gallon
milk: 2.5 per gallon
lemonade: 3 per gallon
since Lisa purchases 4 gallons of milk and 2 gallons of ice cream we will multiply that by the unit money for each food respectively:
7.5(2)+2.5(4)+X=34
SIMPLIFY:
15+10+x=34
15+10=25
25+x=34
25-25+x=34-25
x=9
Lisa bought 9 gallons of ice cream
hope this helps!

Hi there!
So if BC and DA are the same, then BA and CD are also the same...
The only one that’s left is BD.
Therefore, the shortest side is BD.
