Question

Evaluate the expression when t = –6.4 and u = –2.8.

Answer 1

-6.4 – 4(-2.8)
-6.4 – - 11.2 = 4.8

Your answer is B: 4.8

Answer 2

The answer is -17.6.
 It is -17.6 because  when there is a number next to a letter you multiply.And 2.8 times 4 equals 11.2. Then you subtract it by -6.4.
so it is -6.4 - 4x2.8
