The length, l (in inches), of a spring is given by l = ( 3 4 ) f + 8 , where f is applied force in pounds. what value of f will produce a length of 40 inches?

0.94N

Step-by-step explanation:

A linear equation relating the force applied to the length increase has been proposed according to the question.

The equation is :

L = 34F + 8

Now we are having a length of 40 inches, we need to know the value of the force that would have made such an increase.

First, we substitute L for 40 in the equation.

40 = 34F + 8

34F = 32

F = 0.94N

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
