Expand and combine like terms.
(8n^2+3n^7)(8n^2-3n^7)= (8n 2 +3n 7 )(8n 2 −3n 7 )

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

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;
