-(-9d + 2.7f + 3.5)
Distributing the “-“ sign

9d + -2.7f + -3.5

Step-by-step explanation:

The distributive property simply is a form of multiplication that allows the sum of two or more numbers with common multiples to be rewritten.

In the case of this expression, our common multiple is the negative sign which implies an understood -1.

So you can write the expression as such:

(-1) (-9d + 2.7f + 3.5)

So to distribute the -1 to each term, we will simply write the expression:

(-1)(-9d) + (-1)(2.7f) + (-1)(3.5)

Which will give us the distributed expression:

9d + -2.7f + -3.5
