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 21 meters. the height of 44 4 fir trees stacked on top of each other is 2424 24 meters taller than one pine tree. how tall are the types of trees that logan genetically engineered?

The height of  fir tree is 9 meters and the height of pine tree is 12 meters.

Step-by-step explanation:

Given : The combined height of one fir tree and one pine tree = 21 meters.

Since, 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.

Then we get the following equations:

Adding (1) and (2) we get

Substitute the value of x in (1), we get

Hence, the height of  fir tree is 9 meters and the height of pine tree is 12 meters.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
