Points B. D. and F are midpoints of the sides of ACE. EC=30 and DF= 23. Find AC. The diagram is not to scale F E D​

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

b is the correct answer

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
