The airplane is 48 feet long in real dimensions.
To find out how long the airplane actually is, we can use the scale and input our amount of inches that it is measured by.
So, 1 inch equals to 6 feet.
Our model plane is 8 inches.
Now, we plug it in.
8 inches = 6(8)
8 inches = 48 feet
Therefore, the length of the real airplane is 48 feet.
48 feet

Answer:
-3
Step-by-step explanation:
We know that both the larger triangle is dialated by some factor.
To start divide the two given sides:
36/24=1.5
This means that the larger triangle is dialated by a factor of 1.5, meaning that all sides of the smaller triangle must be multipled by 1.5 to get the larger triangle.
By knowing that we can multiply 3x-7 by 1.5 and set it equal to 6x-6.
1.5(3x-7)=6x-6
4.5x-10.5=6x-6
-6x+4.5x=10.5-6
-1.5x=4.5
x=(4.5)/(-1.5)
x= -3
