The monthly rate is 3.6 inches per month.

So,

3.6 inches per months x 6.5 months = 23.4 inches

Answer: The tree grow by 23.4 inches.

Step-by-step explanation: Given that an oak tree grows at a rate of $3\dfrac{3}{5}=\dfrac{18}{5}$ inches per month.

We are to find the length by which the tree grow in $6\dfrac{1}{2}=\dfrac{13}{2}$ months.

We will be using the UNITARY method to solve the given problem.

In one month, the length of the tree grew is

$\dfrac{18}{5}~\textup{inch}.$

Therefore, in $\dfrac{13}{2}$ months, the length of the tree grew is given by

$\dfrac{18}{5}\times\dfrac{13}{2}=\dfrac{117}{5}=23.4~\textup{inches}.$

Thus, the tree grow by 23.4 inches.

Answer:

Zeroes : 1, 4 and -5.

Potential roots: $\pm 1, \pm 2, \pm 4, \pm 5, \pm 10, \pm 20$ .

Step-by-step explanation:

The given equation is

$x^3-21x=-20$

It can be written as

$x^3+0x^2-21x+20=0$

Splitting the middle terms, we get

$x^3-x^2+x^2-x-20x+20=0$

$x^2(x-1)+x(x-1)-20(x-1)=0$

$(x-1)(x^2+x-20)=0$

Splitting the middle terms, we get

$(x-1)(x^2+5x-4x-20)=0$

$(x-1)(x(x+5)-4(x+5))=0$

$(x-1)(x+5)(x-4)=0$

Using zero product property, we get

$x-1=0\Rightarrow x=1$

$x-4=0\Rightarrow x=4$

$x+5=0\Rightarrow x=-5$

Therefore, the zeroes of the equation are 1, 4 and -5.

According to rational root theorem, the potential root of the polynomial are

$x=\dfrac{\text{Factor of constant}}{\text{Factor of leading coefficient}}$

Constant = 20

Factors of constant ±1, ±2, ±4, ±5, ±10, ±20.

Leading coefficient= 1

Factors of leading coefficient ±1.

Therefore, the potential root of the polynomial are $\pm 1, \pm 2, \pm 4, \pm 5, \pm 10, \pm 20$ .
