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 pine tree is 2121 meters. the height of 44 fir trees stacked on top of each other is 2424 meters taller than one pine tree. how tall are the types of trees that logan genetically engineered? each fir tree is meters tall and each pine tree is meters tall.

Fir trees are 9 meters and the pine trees are 12 meters tall.

Step-by-step explanation:

Let the height of the fir tree = x and the height of the pine tree = y (in meters).

It is given that the combined height of both the trees is 21 meters.

That is,

Also, the height of 4 fir trees is 24 meters more than that of the pine tree.

That is, i.e.

So, we get the system of equations,

x+y=21

4x-y=24

Adding both the equations, gives us,

5x = 45 i.e. x=  9.

So, x+y=21 ⇒ y= 21 - x ⇒ y= 21 - 9 ⇒ y= 12.

Thus, the fir trees are 9 meters tall and the pine trees are 12 meters tall.
