Answer:

3(7x + 5y)

Step-by-step explanation:

the highest common factor for this equation is 3, as 21/3 = 7 and 15/3 = 5, and 5 and 7 have no more common factors:

thus - > 21x + 15y = 3(7x + 5y)

<h3>What is Algebra?</h3>

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

There are 46 children going to a party. 18 will wear black costumes, 12 will wear orange costumes and some will wear both black and orange.

Then the number of children who wear costumes and black & orange. Then we have

⇒ 46 - 18 - 12

⇒ 46 - 30

⇒ 16

Half of the guests will go in costumes that are neither black nor orange. Then we have

⇒ 16 / 2

⇒ 8

Then the number of the children who orange and black will be  

⇒ 16 - 8

⇒ 8

The number of children who wore both orange and black will be 8.
