Answer:
The answer is 6cm
Step-by-step explanation:
2cm(the one on top) and 4cm are directly opposite the unknown side which is the same when being cut horizontally so therefore the unknown side is equal to 2cm+4cm which is = 6cm
-4r - 11 = 4r + 21
-4r -4r = 21 + 11
-8 = 32 (Divide both sides by -8)
/ /
-8 -8
= -4
14
25 + 14 = 14 + 25
39 = 39
44
24 divided by 6= 4
2x4=8
3x4=12
24+8+12=44
