Answer:
C
Step-by-step explanation:
Because you should be subtract each other by 20x to transfer from side to another side.
Y - 23 = - 6 ( x + 2 )
Y - 23 = - 6x - 12
Y = - 6x + 11
Y + 6x = 11
Thanks me if it is correct !!
Answer:
your picture doesnt show all the answers but it doesnt matter well just count it
surface area = (length x width) + (width x height) + (height x length) and the answer we times it by 2 (cuz they are 6 sides in a prism)
so 4 x 5 + 5 x 10 + 10 x 4 = 110
110 x 2 = 220in²
