Answer:
225
Step-by-step explanation: if you simply multiply 300 by 3 you get 900 and dividing it you get 225 or you can simply divided 300 by 4 and get 75 before multiplying by 3 for 225.
3(x + 4) = 3x + 4
3x + 12 = 3x + 4
3x - 3x = 4 - 12
0 = -8 (incorrect....no solution)
little tip ...
if it ends with a variable equaling a number, like x = 2 or y = 4, then there is 1 solution.
if it ends with something unequal with no variable, like 0 = -4 or 5 = 7, then there is no solution.
if it ends with something equaling with no variable, like 2 = 2 or 5 = 5, then there is infinite solutions.
I'm going to assume the 4 and 3 are exponents and the expression is 
.
The first step is to separate the coefficients of 3 and -6 from the variables and to multiply those as normal:
As for the variables, you want to recognize that 
means 
and 
means 
, so
In total, there are 7 a's being multiplied, so
Putting this all together, we have:
It would be 1.3 bescuse its only 2 significant figures
