30 + ab + 6b + 5a = 5(a+6) + b(a+6) = (b+5)(a+6)
-2a plus 3b
14a - 4a + 5a - 3a = 12a
5a + 4b - 3a =(5a - 3a) + 4b =2a + 4b =2 (a + 2b)
4a + 3c - 2b - c + a - b = 5a - 3b + 2c
it think ot is 5(a+b)
It simplifies to 5a+4 !
10a + 5b
The given expression can be simplified to: 3b-a
30 + ab + 6b + 5a = 5(a+6) + b(a+6) = (b+5)(a+6)
-2
-2a plus 3b
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
4a + 7
a + b + c = 180 b = 3a c = 5a Substituting the values of b and c into the first equation. a + 3a + 5a = 180 or 9a = 180 so that a = 20 then b = 3a = 3*20 = 60 and c = 5a = 5*20 = 100
14a - 4a + 5a - 3a = 12a
5a(a+2b+b²)
