It is definitely not equal to it. It's greater.
Answer:
To prove:
X+Y.Z=(X+Y).(X+Z)
Taking R.H.S
= (X+Y).(X+Z)
By distributive law
= X.X+X.Z+X.Y+Y.Z --- (1)
From Boolean algebra
X.X = X
X.Y+X.Z = X.(Y+Z)
Using these in (1)
=X+X(Y+Z)+Y.Z
=X(1+(Y+Z)+Y.Z --- (2)
As we know (1+X) = 1
Then (2) becomes
=X.1+Y.Z
=X+Y.Z
Which is equal to R.H.S
Hence proved,
X+Y.Z=(X+Y).(X+Z)
Answer:

Step-by-step explanation:
y is equal to 2 and goes up to infinity
Answer:
-$200
Step-by-step explanation:
Given that:
Net earning per bouquet for the month= - $2.50
On a particular day of the month, 20 bouquet was sold ;
Net earning for the day:
Net earning per bouquet * number of bouquet
-$2.50 * 80
= $200
Hence, net earning for Tuesday = - $200
(a)

(b)we have 4 terms in this expression.
(c)+12 is the leading coefficient in

(d) constant is -45
