Answer:
B & C
Step-by-step explanation:
I'm not sure if you can have two answers but both of them are linear. A And D aren't because they have absolute value
![\frac{4}{ \frac{3}{7} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B%20%5Cfrac%7B3%7D%7B7%7D%20%7D%20)
= 4 ÷
![\frac{3}{7 }](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B7%20%7D%20)
= 4 ×
![\frac{7}{3 }](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B3%20%7D%20)
=
![\frac{28}{3 }](https://tex.z-dn.net/?f=%20%5Cfrac%7B28%7D%7B3%20%7D%20)
Hope this helped! Ask me if there's any part of the working you don't understand :)
Answer:
C
Step-by-step explanation:
Using Pythagoras' identity in right triangle BPO
with PB = 4 ( half of AB ) and OB = 5 ( radius of circle )
OP² + 4² = 5²
OP² + 16 = 25 ( subtract 16 from both sides )
OP² = 9 ( take the square root of both sides )
OP =
= 3
