1 answer

To simplify the expression (3y5x4)(10+2x4y), we first distribute the negative sign across the second set of parentheses:

3y5x4102x+4y

Next, we combine like terms. Let's group the terms:

  • For y terms: 3y+4y=7y
  • For x terms: 5x2x=7x
  • For constant terms: 410=14

Putting it all together, we have:

7y7x14

Therefore, the equivalent expression is:

7y7x14
