The ratio of the perimeter of triangle PQRto the perimeter of rectangle ABCD is 5:9. B (x - 3) cm (3x - 5) cm (4x - 21 cm (4x + 3) cm R (2x + 2) cm a. Write algebraic expressions for the perimeters of triangle PQR and rectangle ABCD. b. Write a linear equation using the algebraic expressions written in part a. Then solve for x. c. Find the area of rectangle ABCD.​

step-by-step explanation:

b and c

it would be 3 ÷by 6 because the number on each side

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;
