Step-by-step explanation:
correct answer-C ( rhombus)
The temperature decreased so you would subtract the amount from the original temperature.
The answer would be:
-15 - 10 = -25
When you factor the equation...
r^2-4r-77
r^2+7r-11r-77
r(r+7)-11(r+7)
(r-11)(r+7) so each parenthetical term is a dimension.
Note that r>11 though for any possible real solution.
