Step-by-step explanation:
<u>Step 1: Define expression</u>
64 + [40 ÷ (4 - 7 + 8)] - 10
<u>Step 2: Evaluate</u>
- Brackets - Parenthesis - Subtract: 64 + [40 ÷ (-3 + 8)] - 10
- Brackets - Parenthesis - Add: 64 + [40 ÷ 5] - 10
- Brackets - Divide: 64 + 8 - 10
- Add: 72 - 10
- Subtract: 62
And we have our final answer!
Answer:
5sqrt3
Step-by-step explanation:
Using the pythagorean theorem, we have a^2+4^2=9^2
a^2 + 16 = 81
a^2 = 75.
a = sqrt75.
75 = 25*3. 25 is a perfect square, so sqrt75 = 5sqrt3
