The width of a rectangular field is 20 centimeters. The perimeter is at least 648 centimeters. Write and solve an inequality to find the possible lengths of the field.

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.

Ais the correct answer - trinomial (three parts) degree of 2 (highest exponent being 2)hope this , and mark brainliest!
