Question

Please help me with maths


`xy + 3x +8y + 24`
If the card above is the product of Emily's and Ros's ages, state their ages, respectively. ​

Answer 1

Given expression:

• xy + 3x + 8y + 24

You may factor this as follows:

• xy + 8y + 3x + 24 =
• y(x + 8) + 3(x + 8) =
• (x + 8)(y + 3)

We have the product of x + 8 and y + 3 and we can state that:

• Emily's age = x + 8
• Ros's age = y + 3
• (or vise versa)
