Amodel plane has a scale of 1 in: 6yd if the model plane is 3in tall then how long is the real plane?

First we have to simplify yards to inch. 3 Feet is in a yard so therefore 36 inches in a yard. Then you would use the scale to 1 to 6 and simplify to get the answer. I am a math teacher. My goal is to guide the students and not give them the answer. My job is to train you guys and learn. Not just to play Fortnite so yeah. Hope this helps.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
