7. The expression (10x3 -5x2 + 12) - (4x3 + x2 - 7x + 3) is simplified into the form ax3 + bx2 +cx + d. Find the numerical values of each of the coefficients of the simplified polynomial expression. a= b =c= d=

there is no points to select.

step-by-step explanation:

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;
