Since the question is 3(2a), then just write it out. 3(2a) is 2a+2a+2a or 6a.
The multiplicative inverse of -2a is 1/(-2a) = -1/2a
a-^2a-b^-a-b
2a + 2b = c subtract 2a from both sides 2a - 2a + 2b = c - 2a 2b = c - 2a divide both sides by 2 (2/2)b = (c - 2a)/2 b = (c - 2a)/2 --------------------
a/2a^2 You can take "a" out of both of those. It leaves you with 1/2a
In mathematical terms, "2a 2a" typically implies the expression ( 2a \times 2a ), which can be simplified to ( 4a^2 ). This is derived from multiplying the coefficients (2 and 2) and adding the exponents of ( a ) (1 + 1). Therefore, the final result is ( 4a^2 ).

This is very easy questions lets solve it -2a - 9 = 39? Add both site 9 -2a - 9 +9= 39+9 Now Simplyfy -2a - 9 +9= 39+9 -2a= 48 devide both side with same factors -2a/-2= 48/-2 a= -24

The multiplicative inverse of -2a is 1/(-2a) = -1/2a
a-^2a-b^-a-b
a + a + a - 2a = 3a - 2a = a
