Answer: B) It represents the product of two irrational numbers and is equivalent to an irrational number.
Step-by-step explanation:
1. By a definition an irrational number cannot be written as a simple fraction.
2. Keeping this information on mind:
(Cannot be written as a simple fraction. It is an irrational number).
(Cannot be written as a simple fraction. It is an irrational number).
3. When you multiply this irrational number, you obtain:
4. 
is an irrational number.
5. Therefore, the answer is the option B,
Answer:
y=9
Step-by-step explanation:
4y-7=29
(add 7 to both sides)
4y=36
(divide both sides by 4)
y=9
-1 = z/3 - 7
Emily's Work:
-1 = z/3 - 7
-1(3)=z/3(3)-7
-3 = z - 7
-3 -7 = z - 7
z = -10
Right away without having to start at the beginning, I see that she has made a mistake at the 4th-5th line of work.
Instead of adding 7 to both sides, she subtracts it and still leaves it in and doesn't fully finish the equation, as it would really be z-7 = -10
In order to solve it, follow these steps:
Rewrite the initial equation as follows:
x/3 - 7 = -1
Multiply both sides by 3
x/3(3)-7(3)=-1(3)
x - 21 = -3
Add 21 to both sides
x = 18
