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.​

a² + b²= c²

24² + 7² = c²

c= 25

5/20 so 25%

step-by-step explanation:

i think its doubled. let me know

step-by-step explanation:

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
