The area of a triangle varies jointly with the height of the triangle and the length of its base. The area of one triangle is 270 square centimeters when its height is 30 centimeters and its base length is 18 centimeters. What is the area of a triangle having a
height of 25 centimeters and a base length of 16 centimeters?

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;

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
