R = x(A+B)
distribute
R=Ax+Bx
subtract Ax from each side
R-Ax=Bx
divideby x
(R-Ax)/x =B
Choice C
<span>x is at most –5 or at least 7 is written as
![x \leq -5 \ or \ x \geq 7](https://tex.z-dn.net/?f=x%20%20%5Cleq%20-5%20%20%5C%20or%20%5C%20x%20%5Cgeq%207)

This is an irrational number
Sorry this took a while but it should be the last option for it to be correct.
Answer: AI:EF
Step-by-step explanation:
1. By definition, the diameter of a circle is twice the radius, then:
D=2r
Where D is the diameter and r is the radius:
2. The AI is the lenght of the radius of the circle and EF is the length of the diameter of the circle. Keeping this on mind you have:
or 1:2
3. Then, AI and EF form the ratio:
1:2
