Answer:
The candle must burn at 2cm per hour in order to be 6cm tall after 4 hours. I know this because the candle has to burn 8cm in 4 hours and that amounts to 2cm per hour.
Step-by-step explanation:
Lets solve!
We have to find out how much of the candle needs to be burned!
14cm - 6cm = 8cm
The candle must burn 8cm in 4 hours!
Lets find out how much the candle burns in 1 hour.
= 2cm per hour

Step-by-step explanation:
I don't know for sure but I hope it's correct.
Use the estimate but that should be more than the exact price
<h2>1.
The "required option c) 45" is correct.</h2><h2>
2. The value of 8 − 2⋅3 + 7 = 9</h2><h2>
3. The required "option c) 45" is correct.</h2><h2>
4. The required "option a) 40" is correct.</h2><h2>
5. The value of 
= 8</h2>
Step-by-step explanation:
1. We have,
+ 20
To find, the value of + 20 = ?
∴ + 20
= 5 × 5 + 20
= 25 + 20
= 45
Thus, the "required option c) 45" is correct.
2. We have,
8 − 2⋅3 + 7
To find, the value of 8 − 2⋅3 + 7 = ?
∴ 8 − 2⋅3 + 7
= 8 - 6 + 7
= 15 - 6
= 9
Thus, the value of 8 − 2⋅3 + 7 = 9
3. We have,
To find, the value of = ?
∴
= 6 × 6 + 3 × 3
= 36 + 9
= 45
Thus, the required "option c) 45" is correct.
4. We have,
To find, the value of = ?
∴
= 2 × 2 × 2 + 4 × 8
= 8 + 32
= 40
Thus, the value of = 40
Thus, the required "option a) 40" is correct.
5 . We have,
To find, the value of = ?
∴
= 3 × 3 - 2 × 3 + 5
= 9 - 6 + 5
= 14 - 6
= 8
Thus, the value of = 8
