The distributive property is used to get the equivalent expression
Step-by-step explanation:
The properties on mathematical expressions are used to simplify or elaborate the expressions.
One of the propoerties is distributive properties
The distributive property states that:
Let a, b and c be three integers then
a(b+c) = ab+ac
The property can be used both ways

Answer:
Step-by-step explanation:
∠1 and ∠2 are vertical angles.
∠1 = ∠2
<u>Part A:</u>
<u></u>
Create an equation and solve for x.
20x + 21 = 30x - 29
Add 29 and -20x on both sides.
20x + 21 + 29 - 20x = 30x - 29 + 29 - 20x
Simplify the equation.
50 = 10x
Divide both sides by 10.
=
Simplify the equation.
5 = x
Switch sides.
x = 5
<u>Part B:</u>
<u></u>
Let x = 5
20(5) + 21
Distribute.
100 + 21
Add.
= 121
Since both angles are vertical angles, they are equal.
∠1 = 121°
∠2 = 121°
Answer:
The probability that M produces a word that looks like a byte is .
Step-by-step explanation:
It is given that a message source M of a digital communication system outputs a word of length 8 characters.
The characters drawn from the ternary alphabet {0,1,2}, and all such words are equally probable.
Total possible outcomes is
We need to find the probability that M produces a word that looks like a byte (i.e., no appearance of ‘2’). It means only 0 and 1 are included in the word.
Total favorable outcomes is
The formula for probability is
Therefore the probability that M produces a word that looks like a byte is .
