Solve the equation using the given values: x= -2.5; y= -7.51. 2xy + 2x²

Let hh represent the number of hummingbirds and ss represent the number of sunbirds that must pollinate the colony so it can survive until next year. 6h+4s > 746h+4s> 74 this year, 88 hummingbirds pollinated the colony. what is the least number of sunbirds that must pollinate the colony to ensure that it will survive until next year?

If a || b and e || f , what if the value of y ?
