Answer:

The correct answer is P = 24 + 8x.

Step-by-step explanation:

First, we must express the length and width of the frame.

Length = 7 + 2x

Width = 5 + 2x

The perimeter is the sum of the four sides of the frame.

P = 2 * (7 + 2x) + 2 * (5 + 2x)

P = 14 + 4x + 10 + 4x

P = 24 + 8x

In this way, we express the perimeter (P) of the frame.

Have a nice day!

How to solve this problem
Slav-nsk [51]

Answer:

8.95

Step-by-step explanation:

here we are going to use pythagoras theorem

a² +b² =c²

the vertical can be taken as a and horizontal as b

4² +8²=c²

this is the same as

c²= 4²+ 8²

c²= 16+ 64

c²=80

to get rid of the square we shall put both sides under a root

\sqrt{c ^{2} }  =  \sqrt{80}

c = 8.95

12. The point P lies on a line through the midpoint of AB and perpendicular to AB. If AP=15 in., what is the length PB? How do y
Mekhanik [1.2K]

Answer:

PB = 15

Step-by-step explanation:

A midpoint is a point in the center of a line. Since P is the midpoint of AB, the length of AP = PB. Therefore, if AP = 15, PB = 15.

horrorfan [7]

Answer:The number of words that she would still have to type to finish her essay is 1000

Step-by-step explanation:

Karen is typing a 4,000 word essay. She can type at about 30 words per minute. This means that if her rate remains constant, the total number of minutes that it will take her to finish would be

4000/30 = 133.33 minutes.

If she types for 45 minutes on Monday, it means that the total number of words that she typed on Monday would be

45 × 30 = 1350 words

If she types for 55 minutes on Tuesday, it means that the total number of words that she typed on Tuesday would be

55 × 30 = 1650 words

Total number of words typed on Monday and Tuesday would be

1350 + 1650 = 3000 words

The number of words that she would still have to type to finish her essay would be

4000 - 3000 = 1000 words
