Sagot :

To solve the expression [tex]\( 10. \ (5+4-2) \times (-2) \)[/tex], follow these steps:

1. Evaluate the expression inside the parentheses:
[tex]\[ 5 + 4 - 2 \][/tex]
Start by adding 5 and 4:
[tex]\[ 5 + 4 = 9 \][/tex]
Then, subtract 2 from 9:
[tex]\[ 9 - 2 = 7 \][/tex]
So, the result inside the parentheses is 7.

2. Multiply this result by [tex]\(-2\)[/tex]:
[tex]\[ 7 \times (-2) \][/tex]
Multiplying 7 by [tex]\(-2\)[/tex] gives:
[tex]\[ 7 \times (-2) = -14 \][/tex]

Therefore, the result of the expression [tex]\( (5+4-2) \times (-2) \)[/tex] is [tex]\(-14\)[/tex].

The correct answer is:
B. [tex]\(-14\)[/tex]
