Felix surrounds a 12 in. by 8 in. photo with a frame that is x inches wide. Which quadratic function represents the combined area A of the picture and the frame?

A. A(x) = x^2 + 20x + 96

B. A(x) = x^2 + 40x + 96

C. A(x) = 4x^2 + 20x + 96

D. A(x) = 4x^2 + 40x + 96

Answers

Answer 1

Answer:

D: A(x) = 4x² + 40x + 96

Step-by-step explanation:

Dimensions of photo is;

Length; L = 12 inches

Width; W = 8 inches

Now, this picture is surrounded by a frame that is "x" inches wide. Thus, new dimensions are;

L_new = 12 + x + x = 2x + 12

W_new = 8 + x + x = 2x + 8

New area is;

A_new = (2x + 12) × (2x + 8)

A_new = 4x² + 24x + 16x + 96

A_new = 4x² + 40x + 96

Rectangle Y.

Step-by-step explanation:

Find the perimeter of both rectangles.

If you want to find rectangle X, the breadth of the rectangle but the length of it isn't the same since it has been shortened, and since it covers half of the card for length...

Length = 14 ÷ 2 = 7cm

Perimeter = 6cm + 6cm + 7cm + 7cm = 26cm (Rectangle X)

Now, let's find perimeter for rectangle Y.

The length for the rectangle is the same as it isn't shortened or anything else, but the breadth is different as it have been shortened, since it covers half of the card for breadth...

Breadth = 6 ÷ 2 = 3cm

Perimeter = 3cm + 3cm + 14cm + 14cm = 34cm

(Rectangle Y)

Explaination: Rectangle Y will have the longer perimeter, (add in the solution that I wrote for rectangle X and Y)

Cost of a lizard: $36.50
Markup: 70%
Discount: 53%

Can anyone answer this with work or a detailed explanation? I think I’ve got the answer but I want to be sure.

Answers

Answer:

Cost after markup = $62.05

Cost after discount = $29.18

Step-by-step explanation:

It is given that:

Cost of lizard = $36.50

Mark up = 70% = 70/100 = 0.7

Markup = 0.7 * 36.50

Markup = $25.55

Cost after markup = 36.50 + 25.55 = $62.05

Discount = 53%

Discount = 0.53 * 62.05

Discount = $32.87

Price after discount = 62.05 - 32.87 = $29.18

Therefore,

Cost after markup = $62.05

Cost after discount = $29.18

Is either x = 18 or x = 14 a solution to x – 8 < 9? A. They are both solutions B. x = 18 is a solution, but x = 14 is not ОО O C. Neither is a solution D. X= 14 is a solution, but X-18 is not​

Answers

Answer:

Answer is D

Step-by-step explanation:

u have two given values of x

x=18 and x=14

put them in the given equation x-8<9

1.FIRST put x = 18

that is (18)-8<9

10<9--->THIS IS INCORRECT BECAUSE 10 IS MORE THAN 9

2.SECOND put x = 14

that is (14)-8<9

6<9---->THIS IS CORRECT SINCE 6 IS LESS THAN 9.

A movie theater charges \$10.50$10.50dollar sign, 10, point, 50 per ticket and \$5$5dollar sign, 5 per bucket of popcorn. You never buy the popcorn because you think it's too expensive.
Is the total price you pay proportional to the number of tickets you buy?

Answers

Answer:

yes

Step-by-step explanation:

Let's make a table to see the total price for different numbers of tickets.

Number of tickets 111 222 333

Total price \$10.50$10.50dollar sign, 10, point, 50 \$21$21dollar sign, 21 \$31.50$31.50dollar sign, 31, point, 50

Hint #22 / 4

For each number of tickets bought, let's write the relationship of total price to number of tickets as a ratio in simplest form.

\dfrac{\$10.50}{1} = \$10.50 ~~~~~~~~~\dfrac{\$21}{2} = \$10.50 ~~~~~~~~~\dfrac{\$31.50}{3} = \$10.50
