Hello!
Explanation:
This question's it's about the order of operations. It stands for parenthesis, exponents, multiply, divide, add, and subtract. It can also go left to right.
Do parenthesis first.
![1+2=3](https://tex.z-dn.net/?f=1%2B2%3D3)
![(3-5)*2-8](https://tex.z-dn.net/?f=%283-5%29%2A2-8)
![-2*2-8](https://tex.z-dn.net/?f=-2%2A2-8)
Multiply left too right.
![-2*2=-4](https://tex.z-dn.net/?f=-2%2A2%3D-4)
![-4-8](https://tex.z-dn.net/?f=-4-8)
![=-12](https://tex.z-dn.net/?f=%3D-12)
Add/subtract left too right.
![1+2(-12)](https://tex.z-dn.net/?f=1%2B2%28-12%29)
Multiply left to right.
![2(-12)=-24](https://tex.z-dn.net/?f=2%28-12%29%3D-24)
![1-24=-23](https://tex.z-dn.net/?f=1-24%3D-23)
Answer: ![\boxed{=-23}](https://tex.z-dn.net/?f=%5Cboxed%7B%3D-23%7D)
Hope this helps!
Answer: $9.64
Step-by-step explanation:
RT = TU
so
m<R = m<U
m<R = 1/2(180 - 114)
m<R = 1/2(66)
m<R = 33
so m<U = m<R = 33
m<SVU = 180 -(31+33)
m<SVU = 180 - 64
m<SVU = 116
x = 180 - 116
x = 64
answer
C. 64
Here is your answer! Hope this helped
A and C are irrational.
We know that B is rational because it's just asking 8 - 5, which is 3.
There is, however, no perfect square root of 73 or 56, and so the answer will be irrational.
