Answer:
A) (0,5)
Step-by-step explanation:
Coordinate point (0,5) lies within the bounded blue region
Answer:
D
Step-by-step explanation:
To determine the roots equate the factors to zero, that is
(x + 2)(x² + 7x + 10) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x² + 7x + 10 = 0
(x + 2)(x + 5) = 0
x + 2 = 0 ⇒ x = - 2
x + 5 = 0 ⇒ x = - 5
roots are x = - 5 and x = - 2 with multiplicity 2
