Nikolas and Angela were trying to solve the equation:

mario62 [17]

Answer:

zero product property (Angela)

Step-by-step explanation:

Hi there !

(Angela)

3x² + 10x = 0

x(3x + 10) = 0

x = 0 => x₁ = 0

3x + 10 = 0 => 3x = - 10 => x₂ = - 10/3 = - 3 1/3

Good luck !

Evergreen Wildlife Preserve has 110 animals, and 66 of them are birds of prey. What percent of the animals are birds of prey?

Korolek [52]

Answer:

60%

Step-by-step explanation:

let ,x% is birds of prey

total animals=110

birds of prey=66

then,

x%of 110=66

x/100×110=66

110x/100=66

1.1x=66

x=66/1.1

x=60%

I'm not sure if this is correct.
