Question

What is the value of 2|C| + 3|D|?

A. 32
B. 9
C. 13
D. 33

Answer 1

D. 33

Explanation:

2|C| + 3|D|

=2|-6| + 3|7|

= 2(6) + 3(7)

= 12 + 21

= 33

Answer 2

For this case, we must indicate the value of the following expression, knowing the values of C and D respectively.

`2 | C | + 3 | D |`

Looking at the number line we have to:

`C = -6\\D = 7`

By definition, we have to:

`| a | = a`

So:

`2 | -6 | +3 | 7 | =\\2 * 6 + 3 * 7 = 12 + 21 = 33`

Answer:

33

Option D
