12V 5A = 12V 5000mA
5 Amps
It is the same as: 9a -4a = 5a
A+5=-5a+5 A=-5a+5-5 (bring one of the 5 over)(not necessary) A=-5a (if big and small letters are the same, A=a=0; if not, when A=35,a=-7)
2a + 3a = 5a
The GCF is 5a.
5a times 5a would equal 25a^2.
5a = a + a + a + a + a
5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2
(5a)^2 or a^2+10a+25
5a or 4a squared
10a You can multiply the constants(numbers) if they have the same variable(letters.)
