Answer:
4 feet
Step-by-step explanation:
the 9 part of the ratio relates to 18 feet , then
18 ÷ 9 = 2 feet ← value of 1 part of the ratio , then
2 parts = 2 × 2 feet = 4 feet ← length on scale drawing
Expand: -7/3(x-1)+2: 13/3-7x/3
expand: 4(2-x): 8-4x
13/3 - 7x/3 =8-4x
13/3 -7x/3 -13/3 = 8-4x -13/3
-7x/3=-4x+11/3
-7x/3 * 3= -4x*3+11/3*3
-7x=-12x+11
-7x+12x=-12x+11+12x
5x=11
5x/5=11/5
x=11/5
Based on time conversion, the age of a teacher who is 50 years old in seconds is 1577880000 seconds.
<h3>What is the age of a teacher who is 50 years in seconds?</h3>
The age of the teacher in years is converted to seconds as follows:
- 60 seconds = 1 minute
- 60 minutes = 1 hour
- 24 hours = 1 day
- 3651/4 days = 1 year
Thus:
50 years to seconds will be:
50 × 365.25 × 24 × 60 × 60 = 1577880000 seconds.
Therefore, the age of a teacher who is 50 years old in seconds is 1577880000 seconds.

Answer:
12x^3 -28x^2 -21x +30
Step-by-step explanation:
1) Distribute!
(6x-5)(2x^2-3x-6) = 12x^3 -18x^2 - 36x -10x^2 +15x+30
2) Combine like terms!
12x^3 -18x^2 - 36x -10x^2 +15x+30 = 12x^3 -28x^2 -21x +30
Answer is:
12x^3 -28x^2 -21x +30
