4 quarts is 1 gallon
6 pints is 0.75 gallons
4 cups is 0.25 gallons
if you add all of those you would get 2 gallons
so she would need 1 more gallon of lemonade
Answer:
Step-by-step explanation:
So 1 is infinite solutions, because -32.4 is equal to -32.4 no matter what you do to it now, because adding, subtracting, whatever will not change teh fact that these are equal because the stuff has to be done on both sides. the solutions for this are INFINITE.
If you have a lot of Pythagorean triples memorized, then you'd probably know immediately, but if not, then you can use the Pythagorean Theorem to calculate each one:
A.: 7^2+9^2=49+81 which is not equal to 13^2, or 169
B.: 5^2+12^2=25+144 which is not equal to 14^2, or 196
C.: 8^2+15^2=64+225=17^2=289
D.: 9^2+12^2=81+144 which isn't equal to 14^2, or 196
Therefore, the correct answer is C.
