0 or 6
Step-by-step explanation:
2aa = 12a
2a² = 12a
Subtract 12a from both sides.
2a² - 12a = 0
Factor left side of equation.
2a(a - 6)=0
Set factors equal to 0.
2a = 0
a =
a - 6 = 0
a = 6
answer: 42
use a calculator to find that 845/73 = 11.575
the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.
subtract that result from 845 to get 845 - 803 = 42
