14 + 7 * 54 / 6 - 7
Use PEMDAS
There are no parenthesis nor exponents so move on to multiplying and dividing work left to right!
14 + 7 * 54 / 6 - 7
14 + 378 / 6 - 7
14 + 63 - 7
77 - 7
70 is your answer
Answer:
10+26x
Step-by-step explanation:
To solve this, work your way from the inner most parentheses to the outer most:
- The inner most parentheses is around 6-2, meaning you solve this first. When you solve this, you get 4.
- The second most inner parentheses is around (1+3 times 4) using PEMDAS, you first solve the multiplication, and then add. Once you solve this, you get 13.
- Next, the outer most parentheses is around (10-5+13x). When you simplify this, you get 5+13x
- Finally, you multiply 2(5+13x). Using distributive property, you get 10+26x as your final simplified answer.
The answer is A I believe
Answer:
Step-by-step explanation:
Always use your imaginary scissor:
Cut the above and below circle and the cylinder role it down-ways like a carpet and you will end up with two circles and a big rectangular.
Surface circle: 7 * 7 * 3,14 = 153.86
Surface carpet: 20 * circle exterior (or the length of the circle)= 20 * 2* 3.14 * 7
Results:
153, 86 * 2 (because we cut 2 circles from the cylinder) + 132,6 = 439.6
Answer: A
