Ryan wants to plant 1/5 packet of seeds in each row of his garden he has four packets of C Ryan uses the expression 1/5 / 4 to find the number of rows you can plant explain what is wrong with his expression then write a equation to show the correct number of rows

The correct expression = 4 / 1/5

The number of rows = 20 rows

Step-by-step explanation:

1/5 Packets of C = 1 row

4 packets of C = x

Cross Multiply

1/5 × x = 4 × 1

The correct expression is

x = 4/ 1/5

x = 4 ÷ 1/5

x = 4 × 5

x = 20 rows

The number of rows Ryan can plant is 20 rows.

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.

i think it is 70
