Problem - gretchen is setting up for a banquet. she has 300 chairs and needs to distribute them evenly among t tables. how many chairs should she put at each table? write your answer as an expression.

The expression is 300÷t.

Step-by-step explanation:

Number  of chairs Gretchen has = 300.

Number of tables Gretchen has = t.

It is given that the chairs are evenly distributed among the given number of tables that is each table will have the equal number of chairs.

The number of chairs she should put can be found by the expression 300÷t.

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.
