In triangle PQR, measurement P = 7x+8 , measurement Q = 8x-10, and measurement R = 7x+6 . List the sides in order from shortest
astra-53 [7]

Answer:

QRP

Q = 8x-10

R = 7x+6

P = 7x+8

Step-by-step explanation:

Let x be any positive integer, say x=2

P=7x+8=(7*2)+8=22 units

Q=8x-10=(8*2)-10=6 units

R=7x+6=(7*2)+6=20 units

From the above, Q is the shortest and P is the longest side. Therefore, the sides arranged from shortest to longest will be Q, R, P
