Final answer:
The solution of the expression {4+[−5(2−4)÷2]}⋅(−2 is −18.
The answer is A
Step-by-step explanation:
To evaluate the expression {4+[−5(2−4)÷2]}⋅(−2), we can follow these steps:
- 1. Simplify the expression inside the brackets: (2−4) = -2.
- 2. Multiply -5 by -2: -5 * -2 = 10.
- 3. Divide 10 by 2: 10 ÷ 2 = 5.
- 4. Add 4 and 5: 4 + 5 = 9.
- 5. Multiply the result by -2: 9 * -2 = -18.
Let's break it down step by step:
1. We start by simplifying the expression inside the brackets, which is (2−4). The result is -2.
2. Next, we multiply -5 by -2. When we multiply two negative numbers, the result is positive. So, -5 * -2 = 10.
3. Then, we divide 10 by 2, which gives us 10 ÷ 2 = 5.
4. Moving on, we add 4 and 5 together: 4 + 5 = 9.
5. Finally, we multiply the result by -2: 9 * -2 = -18.
Therefore, the answer to the expression {4+[−5(2−4)÷2]}⋅(−2) is -18.
Therefore, the answer is -18.
