A two-dimensional net is useful because it flattens the 3-d figure so that you can see all the faces of the figure. You can calculate the area of each face to find the surface area.
It would be -140=x... to get this you would multiply x over 14 by 14... since you did it to one side then you have to do it to the other
Answer:
you got the answer right it's 49

Answer: 200x^2y+640x^2+1010xy+3232x-2380y-7616
Step-by-step explanation:
((8x−14)(5y+16))(5x+34)
((8x−14)(5y+16))(5x)+((8x−14)(5y+16))(34)
200x2y+640x2−350xy−1120x+1360xy+4352x−2380y−7616
200x2y+640x2+1010xy+3232x−2380y−7616
