Trava [24]

Answer: 43 squared units

Explanation:

So the area is the total amount of the inside of the polygon (I’m not good at explaining) and you get your area from using measurements on the sides of the shape for example for a square let’s say the side is 4 and another side is 4 so you multiply that and you get 16 which is the area

So basically since this one is a open polygon you can just count the inside of the poly using the squares

Verdich [7]

Answer:

A) A check for $89.80 for Verizon bill = -89.8

A deposit of $89.80 = +89.8

B) The difference between the two is that,

For the check, money is taken or removed from the account to pay for a bill while

For the deposit, money is added to the account.

Step-by-step explanation:

Ishmael made a mistake in his checkbook. He wrote a check for $89.80 for his Verizon bill but mistakenly recorded it in his checkbook as an $89.80 deposit.

A) Represent each transaction with a rational number

A check for $89.80 for Verizon bill = -89.8

A deposit of $89.80 = +89.8

B) Explain the difference between the transactions.

For the first transaction which is a check for his Verizon bill, using a check on your account means Ishmael wants to withdraw money from his account to pay for the bill. The money in his account will be $89.8 lesser than the initial amount there.

For the second transaction which recording in his checkbook a deposit of $89.80 means $89.80 was added to an account.
