In the town zoo 3/28 of the animals are birds of the birds for 4/15 are birds of prey what fraction of the animals at the zoo are birds of prey

Step-by-step explanation:

In this problem we have to multiply the fractions, because it says that of the animals are birds, and from that fraction are birds of prey. In other words, of are birds of the prey. One strategy to solve this quickly is remembering that "of" is translated into math language as multiplication, so:

Therefore, of the total birds, are birds of the prey.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

ou would have 12 of each
