Answer:
35.7 m.
Step-by-step explanation:
To find the length of string b, you have to multiply 35 by 5. You get 175, and so when it asks how much total string you need for each bottle you must add 175 and 35, which gets you 210. Then, to find how much you need in total for 17 bottles you need to multiply 210 by 17. This gets you 3570 cm, which you can convert to 35.7m.

Answer:
x = 3
Step-by-step explanation:
Given
5x - 3 = 12 ( add 3 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3
As a check
Substitute x = 3 into the left side of the equation and if equal to the right side then it is a solution.
5(3) - 3 = 15 - 3 = 12 = right side
Thus x = 3 is the solution
Where is the question to this or is this the answer
Answer:
the nature of the roots of an equation is real, distinct and irrational
Step-by-step explanation:
Given Data provided in the question according to the question is as follows:
where
a = 2 , b = 8 , c = 3
As we know that
Quadratic expression
Delta = 
= 64 - 24
= 40
Here,
Delta > 0, it does not contain perfect square
Therefore the nature of the roots of an equation is real, distinct and irrational
