<span>When you solved quadratic equations, you created factors whose product was zero, implying either one or both of the factors must be equal to zero. When solving a quadratic inequality,
you need to take more options into consideration. (x + 4) > 0 and (x
+ 3) < 0. One factor must be negative and one must be positive.</span>
Answer:
The bear is 35 years of old now.
Step-by-step explanation:
Leon wanted to know the age of the black bear at the zoo.
He is informed that if he adds 10 years to the age of the bear and then doubles it, the bear would be 90 years old.
Let the present age of the bear is x years.
So, according to the above condition we can write
2(x + 10) = 90

⇒ 2x = 70
⇒ x = 35
So, the bear is 35 years of old now. (Answer)
