Use Pie the method we all learned i really can’t remember but i think it’s 3.14
Add 5ft 7in and 4ft 8in together
5ft 7in + 4ft 8in = 10ft 3in
43.54 divided by 3.5= unit rate

Hi there
a/(a² - 36) + 2/(a-6) = 1/(a+6)
a/(a+6)(a-6) + 2/(a-6) = 1/(a+6)
Now we need to multiply the terms by (a+6)(a-6)
a + 2(a+6) = 1(a-6)
a + 2a + 12 = a - 6
3a + 12 = a - 6
3a - a = -6 - 12
2a = -18
Divide both sides by 2
2a/2 = -18/2
a = -9
Thus, The correct option is A
I hope that's help !
Good luck !
21 times because you need 7/4=1 gallon and 3/4 just for one and 7x3 =21 so need 21/4
