3b2 = 3 divide both sides by 3
b2 = 1
b = 1
12b2 - 8b = 0 4b(3b-2) = 0 4b = 0 and 3b-2 = 0 4b = 0 and 3b = 2 b = 0 and 2/3
(2a + b)(a + 3b)
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3

B squared equals c squared minus a squared then to find B take the square root of you answer for b squared
b is the square root of 5/3
a = 3b - c a + c = 3b - c + c a + c = 3b (a + c)/3 = 3b/3 ( a + c ) / 3 = b Do your homework.
12b2 - 8b = 0 4b(3b-2) = 0 4b = 0 and 3b-2 = 0 4b = 0 and 3b = 2 b = 0 and 2/3
This expression can be factored. ab + 3a + b2 + 3b = a(b + 3) + b(b + 3) = (a + b)(b + 3)
3b2 - 3b = 3b(b - 1)
(2a + b)(a + 3b)
6
It is an equation and the value of b is 3
(a+b)(3b+1)
20+3b = 20 + 3(-6) = 20-18 = 2
If a + b = 6, what is the value of 3a + 3b?
If 3b = 39 thenb = 39/3b = 13.
