Solve each equation 1.0=x^2-7x-18

2. x^2 + 10x = 39

3. 0= x^2-10x+12

4. 2x^2+4x =0

5. 3x^2 -22 +7=0

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.
