As we know that the area of a rectangle is -

length × Breadth

So, here length = (3n+1)

Breadth = (2n-5)

Area of rectangle
= (3n+1)(2n-5)

= 3n(2n-5)+1(2n-5)

= 6n² - 15n + 2n - 5

= 6n² - 13n - 5

Answer) Area of rectangle is 6n² - 13n - 5

Steve has overdrawn his checking account by $27. His bank charged him $15 for an overdraft fee. Then he quickly deposited $100.
REY [17]

Answer:

Step-by-step explanation:

Overdrawn amount =$27

So Steve has negative $27 in the account.

Bank charge =$15 which Steve has to pay to the bank.

So Steve's account has negative $27 plus negative $15.

altogether negative (27+15)= 42.

As he deposits $100, this negative $42 will be deducted from the newly available amount.

so $100-$42 = $58.

Now he is left with $58 in the account

Answer:

3a^{4} - 48

Step-by-step explanation:

Given

(a + 2)(3a² + 12)(a - 2)

= (a + 2)(a - 2)(3a² + 12) ← expand the first pair of parenthesis using FOIL

=(a² - 4)(3a² + 12) ← expand using FOIL

= 3a^{4} + 12a² - 12a² - 48 ← collect like terms

= 3a^{4} - 48
