Example Questions

Example Question #71 : Distributive Property

\(\displaystyle 2(9+4)=\)

Possible Answers:

\(\displaystyle 29\)

\(\displaystyle 26\)

\(\displaystyle 3\)

\(\displaystyle 15\)

Correct answer:

\(\displaystyle 26\)

Explanation:
According to the order of operations, we should take care of the operations in parentheses first. Then find the product:

\(\displaystyle 2(9+4)=2(13)=26\)

Answer: \(\displaystyle 26\)

Example Question #72 : Distributive Property

\(\displaystyle 5(7+13)=\)

Possible Answers:

\(\displaystyle 100\)

\(\displaystyle 25\)

\(\displaystyle 101\)

\(\displaystyle 110\)

Correct answer:

\(\displaystyle 100\)

Explanation:

We perform the addition first because it is in parentheses. The second and final step is the multiplication:

\(\displaystyle 5(7+13)=5(20)=100\)

Answer: \(\displaystyle 100\)

Example Question #73 : Distributive Property

Multiply:

\(\displaystyle y(-2y+3)\)

Possible Answers:

\(\displaystyle -2y^{2}-3y\)

\(\displaystyle -2y^{2}+3y\)

\(\displaystyle 2y^{2}+3y\)

\(\displaystyle -y^{2}+3y\)

Correct answer:

\(\displaystyle -2y^{2}+3y\)

Explanation:

In this problem, you must apply the distributive property and multiply y by each item in the parentheses. 

\(\displaystyle y(-2y+3)\)

Remember that y times y will result in \(\displaystyle y^{2}\)

\(\displaystyle -2y^{2}+3y\)

Example Question #74 : Distributive Property

\(\displaystyle 6(5+2)=\)

 

Possible Answers:

\(\displaystyle 48\)

\(\displaystyle 36\)

\(\displaystyle 30\)

\(\displaystyle 42\)

Correct answer:

\(\displaystyle 42\)

Explanation:

First do the addition, because operations in parentheses take precedent. Then take the product to find the answer:

\(\displaystyle 6(5+2)=6(7)=42\)

 

Example Question #75 : Distributive Property

\(\displaystyle 4(3+11)=\)

Possible Answers:

\(\displaystyle 12\)

\(\displaystyle 56\)

\(\displaystyle 44\)

\(\displaystyle 18\)

Correct answer:

\(\displaystyle 56\)

Explanation:

Order of Operations tells us that the operation in parentheses must be done before the multiplication:

\(\displaystyle 4(3+11)=4(14)=56\)

Answer: \(\displaystyle 56\)

Example Question #76 : Distributive Property

\(\displaystyle 12(8+3)=\)

Possible Answers:

\(\displaystyle 36\)

\(\displaystyle 32\)

\(\displaystyle 96\)

\(\displaystyle 132\)

Correct answer:

\(\displaystyle 132\)

Explanation:
First add the numbers in parentheses, then find the product:
 
\(\displaystyle 12(8+3)=12(11)=132\)

Answer: \(\displaystyle 132\)

Example Question #77 : Distributive Property

\(\displaystyle 9(4+4)=\)

Possible Answers:

\(\displaystyle 80\)

\(\displaystyle 84\)

\(\displaystyle 70\)

\(\displaystyle 72\)

Correct answer:

\(\displaystyle 72\)

Explanation:
You must remember the Order of Operations (PEMDAS): Parentheses Exponents Multiplication Division Addition Subtraction
 
\(\displaystyle 9(4+4)=9(8)=72\)

Answer: \(\displaystyle 72\)

 

 

Example Question #78 : Distributive Property

\(\displaystyle 8(7+3)=\)

Possible Answers:

\(\displaystyle 8\)

\(\displaystyle 24\)

\(\displaystyle 80\)

\(\displaystyle 56\)

Correct answer:

\(\displaystyle 80\)

Explanation:
If you remember the Order of Operations (PEMDAS), this problem can be solved quickly.
 
PEMDAS stands for Parentheses Exponents Multiplication Division Addition Subtraction:
 
\(\displaystyle 8(7+3)=8(10)=80\)

Answer: \(\displaystyle 80\)

Example Question #79 : Distributive Property

Solve using the distributive property:

\(\displaystyle 3(8+7)=\)

Possible Answers:

\(\displaystyle 54\)

\(\displaystyle 45\)

\(\displaystyle 12\)

\(\displaystyle 15\)

Correct answer:

\(\displaystyle 45\)

Explanation:

First multiply 3 by each number in parentheses:

\(\displaystyle 3*8=24\)

\(\displaystyle 3*7=21\)

Then solve equation: \(\displaystyle 24+21=45\)

Answer: \(\displaystyle 45\)

Example Question #80 : Distributive Property

Solve:

\(\displaystyle \sqrt{16}(78)=\)

Possible Answers:

\(\displaystyle 132\)

\(\displaystyle 123\)

\(\displaystyle 213\)

\(\displaystyle 312\)

Correct answer:

\(\displaystyle 312\)

Explanation:

First solve the square root: \(\displaystyle \sqrt{16}=4\)

Then multiply:

\(\displaystyle 4(78)=312\)

Answer: \(\displaystyle 312\)
