Plug the x values into the equation.
For -3 the answer is -11 because 3(-3)-2 = -11
For 1 the answer is 1 because 3(1)-2 = 1
For 5 the answer is 13 because 3(5)-2 = 13
So your points will be (-3,-11), (1,1), and (5,13)

a molecule is measured and the width is 3x10-6 cm. how long will a string of 225 similar molecule be? give your answer in scient

mixer [17]

The length of the molecule is $6.75*10^-^4cm$ in scientific notation.

Data;

Width of molecule = 3*10^-6 cm
Number of molecules = 225

<h3>Length of the molecule</h3>

This can be calculated as the total length of the 225 molecules added together. To do this, we simply multiply both the numbers of the molecules by the width of the molecule.

This becomes;

$3*10^-^6*225 = 0.000675cm = 6.75*10^-^4cm$
