Answer 2

To solve the expression -c² + 5c when c = 0.3, we substitute the value of c into the expression and calculate the result.

Plugging in c = 0.3, we have:

-(0.3)² + 5(0.3)

Simplifying, we get:

-0.09 + 1.5

Adding the two terms, we find:

1.41

Therefore, when c = 0.3, the expression -c² + 5c evaluates to 1.41.
