2a + a = 3a
3a + 2a = 5a
2a2
a x a means that a is multiplied by a. 2a means that a is multiplied by 2. Unless a happens to be 2, a x a will give a different result.The difference is a x (a-2). for example if a = 2, then the difference is zero. If a = 3, the difference is 3The operators are different: 2a = a + a (addition).
a + a = 2a
In mathematics, "2a 2a" typically refers to the expression involving the variable "a" multiplied by 2 twice, which can be interpreted as (2a \cdot 2a). This simplifies to (4a^2) when you multiply the coefficients and the variables. If the context is different, please provide more details for a more accurate interpretation.
2a2
2a + 5a + 3a = 10a
The answer is 2a because of the two a's equal 2a
In order for the formula 3 - 2a = 7 to be solved, the value 2a must equal -4, because 3 - (- 4) = 7. Therefore, a must equal - 2.
-16A
(2A/A)+6 is equal to eight. 2A/A leaves one with 2, since the As cancel out and 2 and 6 is eight.
