Answer:
Perimeter= 34a
Area= 42a
Step-by-step explanation:
Perimeter: 3a + 3a + 3a+ 3a +3a + 5a +5a + 9a = 34a
Area: (3a x 9a) + (3a x 5a) = 42a
f(1) = 12
f(n) = -3•f(n -1) - 2•f(n - 2); for n > 1

B) -4, -12, -28, -60, …
C) -4, 12, -18, 54, …
D) -4, 12, -18, -54, …
Alexander would have to pay $15 for 2 pounds of walnuts after using the coupon. The expression for the cost to buy p pounds of walnuts is (8 * p) - 1.
The price per pound of walnuts that Alexander is buying is $8. If he is buying 2 pounds, without the coupon he would have to pay 2 * $8 = $16. But since he has a $1 off coupon, he would have to pay $16 - $1 = $15.
To formulate an expression for the cost to buy p pounds of walnuts, we consider that each pound costs $8 and there is a $1 off from the total price. So for p pounds, the expression would be (8 * p) - 1.

Alexander would have to pay $15 to buy 2 pounds of walnuts with the coupon. The expression is cost = ($8/pound) x pp - $1.
The functional connection between cost and output is referred to as the cost function. It examines the cost behaviour at various output levels under the assumption of constant technology. An essential factor in determining how well a machine learning model performs for a certain dataset is the cost function. It determines and expresses as a single real number the difference between the projected value and expected value.
Given that, the price per pound of walnuts is $8.
2 pounds x $8/pound = $16
Alexander would get $1 off the final amount.
Thus,
$16 - $1 = $15
So Alexander would have to pay $15 to buy 2 pounds of walnuts with the coupon.
The expression for the cost can be written as:
cost = ($8/pound) x pp - $1
Hence, Alexander would have to pay $15 to buy 2 pounds of walnuts with the coupon. The expression is cost = ($8/pound) x pp - $1.
