The length should be 31 feet and 3 inches
Explanation:
You use a proportion to find the length
Answer:
x = 7 cm.
Step-by-step explanation:
The 2 triangles are similar so corresponding sides are in the same ratio.
Therefore:-
x / 42 = 6/36
x / 42 = 1/6
6x = 42
x = 7 (answer).
Take the square root of both sides
remember to take the positive and negative root
2x+5=-7 or
2x+5=7
solve each
2x+5=-7
subtract 5
2x=-12
divide 2
x=-6
2x+5=7
subtract 5
2x=2
divid 2
x=1
x=-6 or 1
The quantity of water in the tank after 9 days is 19 liters.
<h3>How much water is in the tank after 9 days?</h3>

12 > x+6
Subtract 6 from both sides.
Therefore, 6 > x and x < 6.
