Question

What is 2|u| – |v|, if u = –9 and v = –2?

A. –18
B. 16
C. –20
D. 20

Answer 1

B

Explanation:

Note that the absolute value always returns a positive value, that is

| - 2 | = | 2 | = 2

given

2| u | - | v | with u = - 9 and v = - 2, then

2 | - 9 | - | - 2 |

= 2 × 9 - 2 = 18 - 2 = 16 → B

Answer 2

I believe the answer would be B
