The combined height of one fir tree and one pine tree is 212121 meters. the height of 444 fir trees stacked on top of each other is 242424 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.

Height of fir tree = 9 meters

height of pine tree= 12 meters

Step-by-step explanation:

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.

Let x be the height of fir tree and y be the height of pine tree

Subtract x from both sides

height of 4 fir trees = pine tree +24

Substitute 21-x or y in the above equation

Add x on both sides

Divide by 5 on both sides

x=9

Now plug in 9 for x and find out y

y=12

Height of fir tree = 9 meters

height of pine tree= 12 meters

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
