Question

−4.2(−2.8+4.5)​ hoi de hoi

Answer 1

nice

Explanation:

Answer 2

-7.14

Explanation:

The first rule of PEMDAS is Parenthesis, so you add what is in between them:

-2.8 + 4.5 = 1.7

Your equation now look like:

-4.2 (1.7)

When you have a number before a parenthesis, you have to multiply them:

-4.2 x 1.7 = 7.14

And that's your answer! Hope that made sense.
