Use Boolean algebra to simplify the given Boolean expression. Determine the minimum (i.e. simplest) expression. F(A, B, C) = A.B

klasskru [66]

Answer:C

Step-by-step explanation:

A.B.C+A.B'.C+A'.B.C+A.B.C'

By distributive law : A.B.C+A.B.C' = A.B(C+C')

By complement law: C+C'=1, so

A.B(C+C')=A.B

Therefore the answer will be A.B'.C+A'.B.C+A.B

-5(2b + 7) + b < -b - 11

Stells [14]

-5(2b+7) + b < -b - 11
-10b - 35 + b < -b - 11

- 10b + b - 35 < -b - 11

-9b - 35 < -b - 11

- 9b + b < - 11 + 35

-8b < 24

 $\frac{-8b}{-8} \ \textless \ \frac{24}{-8}$

b < -3

(x+1)(x−1)(x−5)=0 HELP

Svet_ta [14]

Answer:

x³ - 5x² - x + 5

Step-by-step explanation:

(x+1)(x-1)(x-5) = 0

fisrt step:

(x+1)(x-1) = x*x + x*-1 + 1*x + 1*-1 = x² - x + x - 1 = x² - 1

then:

(x+1)(x-1)(x-5) = (x²-1)(x-5)

(x²-1)(x-5) = x²*x + x²*-5 -1*x -1*-5 = x³ - 5x² - x + 5
