Logan genetically engineered a new type of fir tree and a new type of pine tree. The combined height of one fir tree and one pin

shepuryov [24]

Answer:

The types of trees that Logan genetically engineered are fir trees 9 meters tall and pine trees 12 meters tall.

Step-by-step explanation:

Given:

The combined height of one fir tree and one pine tree is 21 meters.

The height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree.

Now, to find the height of types of trees that Logan genetically engineered.

Let the height of fir tree be $x.$

And let the height of pine tree be $y.$

So, the combined height of both the trees:

$x+y=21\\\\x=21-y\ \ \ .....(1)$

As given, the height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree.

Thus,

$4x=y+24$

Now, substituting the value of $x$ from equation (1):

$4(21-y)=y+24$

$84-4y=y+24$

Subtracting both sides by 24 we get:

$60-4y=y$

Adding both sides by $4y$ we get:

$60=5y$

Dividing both sides by 5 we get:

$12=y\\\\y=12\ meters.$

The height of pine trees = 12 meters.

Now, substituting the value of $y$ in equation to get the height of fir trees:

$x=21-y\\\\x=21-12\\\\x=9\ meters.$

The height of fir trees = 9 meters.

Therefore, the types of trees that Logan genetically engineered are fir trees 9 meters tall and pine trees 12 meters tall.

What is the completely factor form of x4+8x2-9

Mademuasel [1]

It takes some trial and error

To find the factored form, you know that the format will look like

(x^n +/- a) (x^n +/- b)

Since the expanded form has x^4, the first part of each expression in parentheses will be x^2  because x^2 * x^2 will give you x^4

Then you have to figure out, how will you get -9 in the expanded form? The "a" and "b" parts of each expression will have to multiply to equal -9.

Factors of -9 will be -3*3 or -1*9 or -9*1

Also, consider the 8x^2 part - as it relates to finding the factors of 9. The parts of the expression that result in  8x^2 in the expanded form ...

a*x^2 + b*x^2 = 8x^2

If you think about this, you know the a and b will = -1 and 9 because you also have to add the expressions with x^2 to get 8x^2, and 3 and 3 would not give you the 8x^2 and neither would nor would -9 and 1.

Final factored form is

(x^2 - 1) (x^2 + 9)
