The science teacher at angela’s school is planning a field trip for all her classes. the number of accompanying adults must be proportional to the number of students. if 30 students go on a field trip, there must be 5 adults. determine the number of adults, a, that need to accompany 84 students on the field trip.

the answer is 37

step-by-step explanation:

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.

168

step-by-step explanation:

i am pretty sure that the answer is 168

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
