Answer:
Step-by-step explanation:
We will start by using the quadratic formula.
We will simplify that and get:
So our answers would be:
Use distance formula
=√(3-3)^2 +(-4-4)^2
=√64
=8
Answer:
5x + 16
Step-by-step explanation:
the first thing you do in this equation is to distribute the 2 into x + 6
you get
2x + 12 + 3x + 4 = ?
then you must put the 2x and the 3x together
5x + 12 + 4
and you can then add the 12 and 4
5x + 16
Elio is right in assuming the relationship between the height and the hours it burns is proportional.
Find the unit rate
14 ÷ 8 = 1.75 cm/h
Divide
21 ÷ 1.75 = 12
You can set this up as an algebraic equation to check the answer.
If the candle is 21 cm tall, it will burn for 12 hours.
Hope this helped you! :)
Step-by-step explanation:
Find w
V = lwh
V ÷ lh = w
V/lh = w
w = V/lh
Option → C
