Oh, dude, it's like asking me for the cool, alternative name for your boring math problem. So, 3a plus 5 is basically the same as saying "three times a, plus five." It's just a fancier way of dressing up your numbers, you know?

An equivalent expression to 3a plus 5 would be 5 plus 3a, as addition is commutative. This means the order of the terms can be switched without changing the result. Another equivalent expression could be 3a + 5, as the addition operation is associative, allowing us to group the terms in any order. Finally, we could also write the expression as 3(a) + 5 to show that the coefficient 3 applies to the variable a.
The expression 9+5 is equivalent.
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
3a + a = 4a Example: a = 5 (3x5) + 5 = 15 + 5 = 20 = 4 x 5
To factor the expression 15a - 25b + 20, we first look for common factors among the terms. The greatest common factor among the coefficients is 5. We can then factor out 5 to get 5(3a - 5b + 4). This is the factored form of the expression 15a - 25b + 20.
