Gelneren [198K]

Answer:

B) 72

Step-by-step explanation:

28+(17x+4)=4+24x

17x+32=24x+4

32=24x-17x+4

32=7x+4

7x=32-4

7x=28

x=28/7

x=4

WGH=17x+4=17(4)+4=68+4=72

Answer:

lol, hello again!

SA = 456 cm²

Step-by-step explanation:

small rectangle SA: 6*4 + 6*8 + 6*4 + 6*8 + 4*8 = 176

large rectangle SA: 2*14 + 2*8 + 2*14 + 2*8 + 8*14 + (8*14 - 8*4) = 280

Total SA = 176 + 280 = 456
