PQ = x - 5, QR = 2x -1, and PR = 21. Find X

7

Step-by-step explanation:

Step 1:

PQ + QR = PR

Step 2:

x - 5 + 2x - 1 = 21

Step 3:

3x - 6 = 21

Step 4:

3x = 27

x = 7

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
