-8/7a
3a2 - 16a + 5 = 3a2 - 15a - a + 5 = 3a(a -5) - 1(a -5) = (3a - 1)(a - 5)
15a + 12 = 3(5a + 4)
Kramer's apartment number is 5B
The GCF is 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)
5a over 6
-8/7a
The GCF is 5a.
5a = a + a + a + a + a
It is 5/3*a - 2/3
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
30-5a = 25
6b-5a = 1
2a - 5a = -3a
5a-20 = -15
