Answer: B
Step-by-step explanation: when you put a + and - together you get a -, so the equation turn into -40-15 which equals -55, so the answe is B
The square root of 24 first find a even root so the square root of 4x6 wich leaves you the 2 square root of 6
When you're dividing fractions, you've got to slip the second fraction then multiply them together. Once you've flipped it, you get
5/6 x 7/3
You then simply multiply the numerators and the denominators
5x7= 35
6x3= 18
Therefore, this becomes 35/18, which can be simplified to 1 17/18
Hope this helps :)
