Answer:

∴ The product of $(x+7)(y+9)$ is $xy+9x+7y+63$.

Step-by-step explanation:

• In context with question asked,
• We have to the product of $(x+7)(y+9)$.
• To find the product of given expression, we have to multiply the brackets.
• Multiplication is one of the important arithmetic operation of mathematics among division, multiplication, addition and subtraction.
• With the help of multiplication, we can find the multiplies of given numbers.
• In multiplication, -ve*-ve=+ve, -ve*+ve-ve.
• The given expression is,

       $(x+7)(y+9)=xy+9x+7y+63$

• ∴ The product of $(x+7)(y+9)$ is $xy+9x+7y+63$.
