-2a^2
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
52 times 2a = 104a
7
a times 2 equals 2a
No. 2a is one thing, 3b is another. If you add them together, they become 2a + 3b. 5ab indicates that multiplication has taken place. 5 times a times b = 5ab
A + 2a = 3a
2a + a = 3a
3a + 2a = 5a
a + a = 2a
-2a^2
Since the question is 3(2a), then just write it out. 3(2a) is 2a+2a+2a or 6a.
2
The answer is 2a because of the two a's equal 2a
2a + 5a + 3a = 10a
If you mean 2a times a and a is a variable, the answer would be 2a2.
