A bookmark has an area of 21 square centimeters. Its perimeter is 20 centimeters. What are the dimensions of the bookmark?

Answers

Answer: The dimensions are 7cm and 3cm.

Step-by-step explanation:

The following equation can be deduced from the question

L × W = 21 ....... i

2L + 2W = 20 .......... ii

Divide equation ii through by 2

(2L + 2W = 20) / 2

L + W = 10 ....... iii

From equation iii

L = 10 - W ......... iv

Put equation iv into I

L × W = 21

(10 - W) × W = 21

10W - W² = 21

W² - 10W + 21 = 0

W² - 7W - 3W + 21 = 0

W(W - 7) - 3(W - 7) = 0

W - 3 = 0

W = 0+3

W = 3 centimeter

Since,

Length × Width = 21

Length = 21/3

Length = 7 centimeters

The dimensions are 7cm and 3cm.

since P and Q share the same letter you're putting “A” in the middle where the two intersect. since U have B and Q have b we're putting it outside. so Q only supposed to have G. P is empty and U now have B,C,D,F,H.

p^1- p complement means everything outside of P so that will be b,c,d,f,g,h.

First, find out how long it'll take Priscilla to make on bracelet. It is given that she can make 2 bracelets in 16 minutes. Divide 16 with 2:

16/2 =8

Priscilla takes 8 minutes to make 1 bracelet. Divide 64 with 8 to find the amount of bracelets Priscila can make:

64/8 = 8

8 bracelets is your answer.

Given: Priscilla makes 2 bracelets in 16 minutes

To Attain: How many Bracelets she will make in 64 minutes?

⠀⠀⠀⠀⠀⠀__________________

Solution:

Firstly, We will divide the 16min with 2 to find the that how many time taken to make 1 bracelets. then we will multiply the rate with 64min to find how many bracelets she will make! Let's do it•

⠀⠀

[tex]:\implies\sf\dfrac{\cancel{16}^{8}}{\cancel{2_1}}[/tex]

x = 2y − 4

7x + 5y = −66

Answers

Answer:

Step-by-step explanation

Substitute 2y-1 for x in the second equation:

7x + 5y = -66

7(2y-4) + 5y = -66

then solve for y:

14y - 28 + 5y = -66

19y = -38

y = -2

Substitute -2 for y in the first equation:

x = 2y - 4

x = 2(-2) - 4

x = -8

The lines intersect at (-8,-2)
