∙ 13y ago-7 7b + 15 = (-34) 7b = (-34) - 15 7b =(-49) b = (-49) / 7 b= (-7)
7b + 15= -34 First, 7b + 15 - 15 = -34 - 15 So, 7b = -49 Then, 7b/7 = -49/7 And finally, b = -7 So b = -7
(b + 8)(b - 1)
It is an equation and the value of b is 3
2B Multiplied by 3 plus B = 7B. Here is how it's worked out. You start with 2B, multiply that by 3 and you get 6B. Now all you have to do is add the last B, therefore adding 1B to equal 7B.
The given expression can be simplified to: 3b-a
-7 7b + 15 = (-34) 7b = (-34) - 15 7b =(-49) b = (-49) / 7 b= (-7)
-58
7b + 15= -34 First, 7b + 15 - 15 = -34 - 15 So, 7b = -49 Then, 7b/7 = -49/7 And finally, b = -7 So b = -7
If: 6b+21 = 7b-21 Then: 6b-7b = -21-21 And: -b = -42 So: b = 42
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
Assuming your equation = 0, then:b3+8b2+7b = 0factor out b:b(b2+8b+7) = 0factor the squared term:b(b+7)(b+1) = 0So the answers are:b = 0b+7 = 0, b=-7b+1 = 0, b=-1
7b + 16 = 5b + 247b - 5b = 24 - 162b = 8b = 4
(b + 8)(b - 1)
b^2 - 7b + 12 = b^2 - 4b - 3b + 12 = b(b -4) -3(b - 4) = (b - 3)(b - 4)
