I think it's 5.67 or 5.7 rounded to the nearest tenth.
To solve this, follow the order of operations, PEMDAS (Parentheses-Exponents-Multiplication-Division-Addition-Subtraction)

So to start off add 4.7 and -7.4 together

-2.1(-2.7)

Then multiply -2.1 by -2.7. Since these are both negative, your answer will be positive.

5.67 is your answer.

Hope this helps!
