Answer:
The first question is the third choice. Divide by two to get proper squaring. Anytime there is a number in front of the x in a situation like that, always divide by that number on both sides first. Then go from there.
The second question is also the third choice. The square root of 64 is 8. It can't be negative because square rooting is always positive unless you want a weird "i" in there. That's for algebra 2 and beyond so don't worry about it mate.

Define their percentage:
----------------------------------
Adam = 100%
Tapiwa = 100 + 5 = 105%
----------------------------------
Find their total percentage:
----------------------------------
100 + 105 = 205
----------------------------------
Find 1%
----------------------------------
205% = 697 liters
1% = 3.4 liters
----------------------------------
Find 100% (Adam):
----------------------------------
100% = 3.4 x 100
100% = 340 liters
----------------------------------
Find 105% (Tapiwa):
----------------------------------
105% = 3.4 x 105
105% = 357 liters
--------------------------------------------------------------------
Answer: Tapiwa = 357 liters and Adam = 340 liters.

Answer:
2a2 + 4a + 7
Step-by-step explanation:
As, - (2a3 - 3a2 + 4a + 6) + (2a3 + 5a2 + 7)
= 2a2 + 4a + 13
The answer is B because the x describes the domain and it can also be the input value
