Simplify: (2x^2 - 9x + 3) + (-7x^2 + 4x - 2)

a. -5x^2 - 13x + 1

b. -5x^2 + 5x - 1

c. 9x^2 - 4x + 1

d. -5x^2 - 5x + 1

probably .5

i can on others if necessary.

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;
