The factors of 15a are 1, 3, 5, 15, and 'a' .
Assuming the missing signs are pluses, that factors to (4a + 3)(a + 3)
The GCF is 1.
Factors of 90 will be factors of 180.

15a + 12 = 3(5a + 4)
The factors of 15a are 1, 3, 5, 15, and 'a' .
Assuming the missing signs are pluses, that factors to (4a + 3)(a + 3)
No
It is already in its simplest form, so it is: 15a + 25
If you mean: 15a = 6a - 90 then the variable a works out as -10. If you mean 15a + 6a - 90, then it equals 21a - 90.
5
Absolutely not.
It cannot be simplified any further, so it is: 5a³ + 15a² + 20a
If it fits you are fine. You are at the same current and the voltage rating is higher.
no (5x3)
No, the British Board of Film Classification (BBFC) uses standard categories such as 15 and 18 for age ratings in the UK, not 15A or 18A. The "A" suffix is not part of the official classification system.
