To draw the 2 dimensional representation, we just "open" the box and flatten it. Once we have it opened, we find the area of each side and add them up for the total surface area. See the pic. Let me know if you have questions. :)
ok so we see that TR is 17 units, so RV is the same amount
3x+2 so 3x=15 so divide both sides by 3 we get x=5
now we know x=5 4x+1=21 and 9x-4=41

Step-by-step explanation:
Answer:
Number of coins that are not nickels = 55 coins
66 = 55 + n
number of nickels in the jar = 11
Step-by-step explanation:
Pennies = 17
Dimes = 12
Quarters = 26
Nickels = n
Total coins = 66
How many of the coins are not nickels?
= Pennies + Dimes + Quarters
= 17 + 12 + 26
= 55 coins
Number of coins that are not nickels = 55 coins
what equation could you use to find n?
Total coins = Pennies + Dimes + Quarters + nickels
66 = 17 + 12 + 26 + n
66 = 55 + n
n = 66 - 55
n = 11
number of nickels in the jar = 11
