I think it’s B I’m sorry if I’m wrong
By the Pythagorean theorem
.. 15^2 = 10^2 +a^2
.. 225 = 100 +a^2
.. 125 = a^2
.. √125 = a
.. 5√5 = a ≈ 11.18
The missing side length is 5√5 cm.

30 plus 10 equals 40, which is the total amount of questions in the test as stated in the question.
Answer: last option.
Step-by-step explanation:
To apply the Distributive property, remember that:
![c(a-b)=ca-cb](https://tex.z-dn.net/?f=c%28a-b%29%3Dca-cb)
Then, applying this, you get:
![-4(x - 2) - 3x = 2(5x - 7) + 6\\\\(-4)(x)+(-4)(-2)-3x=(2)(5x)+(2)(-7)+6\\\\-4x+8-3x=10x-14+6](https://tex.z-dn.net/?f=-4%28x%20-%202%29%20-%203x%20%3D%202%285x%20-%207%29%20%2B%206%5C%5C%5C%5C%28-4%29%28x%29%2B%28-4%29%28-2%29-3x%3D%282%29%285x%29%2B%282%29%28-7%29%2B6%5C%5C%5C%5C-4x%2B8-3x%3D10x-14%2B6)
Combine like terms means that you need to add the like terms.
Therefore, you get:
![-7x+8=10x-8](https://tex.z-dn.net/?f=-7x%2B8%3D10x-8)
You can observe that the expression obtained matches with the expression provided in the last option.
