Mrs. cobb has 8 petunias, 16 carnations, and 20 pansies to plant in flowerpots. if she plants the same number of each type of flower in the flowerpots, how many flowerpots will she use? how many of each type of flower will be in each flowerpot? *

There are 4 flowerpots in which there will be 2 petunias , 4 carnations, 5 pansies.

Step-by-step explanation:

Since we have given that

Number of petunias = 8

Number of carnations = 16

Number of pansies = 20

We need to plants the same number of each type of flower in the flower pots.

so, Greatest number of flower = H.C.F of 8 , 16, 20 = 4

So, there are 4 flowerpots she will use .

Number of petunias in each flower pot =

Number of carnations in each flower pot =

Number of pansies in each flower pot =

Hence, there are 4 flowerpots in which there will be 2 petunias , 4 carnations, 5 pansies.

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.
