Answer 4

Sure, let's solve the expression step by step:

1. Start by simplifying the expressions inside the parentheses:

   • 3 - 4c = -4c + 3
   • 0.5 + 0.2 = 0.7

2. Next, multiply the constants outside the parentheses with the simplified expressions inside: -7 * (-4c + 3) = 28c - 21 14 * 0.7 = 9.8

3. Finally, combine the results of the two multiplications: 28c - 21 + 9.8

Now, we add the constant terms together: 28c - 21 + 9.8 = 28c - 11.2

The final simplified expression is: 28c - 11.2

If you have a specific value for 'c', you can substitute it into the expression to get the numerical result.
