I think it would go like this:[40- 2 (8+2)]=10 I think
Answer:
Step-by-step explanation:
2c + h =16 <- 1
4c + 3h = 34 <-2
1 to 2
3[2c+h = 16]3
=6c +3h = 48 <-3
3 to 2
6c +3h = 48
- 4c + 3h = 34
-----------------------------
2c = 14
c= 7
substitue C=7 to equation 1
2(7) + h =16
14 + h = 16
h = 2
Therefore 7 and 2 is the answer

Step-by-step explanation:
I just used an equivalent fractions calculator.
Please correct me if I'm wrong :)
Use the Pythagorean Theorem
6 feet and 14 feet are the "legs" and the ladder length is the hypotenuse.
hypotenuse^2 = 6^2 + 14^2
hypotenuse^2 = 36 + 196
hypotenuse^2 = 232

ladder length = 15 feet
