A rectangle has side lengths (x + 4) feet and (2x - 2) feet. Write a linear expression in simplest form to represent the perimeter. Find the perimeter if the value of x is 7 feet​

Answers

Answer 1

Answer:

6x + 4, 46

Step-by-step explanation:

Linear expression - (x +4) + (x +4) = 2x +8

2x -2) + (2x-2) = 4x -4                             2x+8 +4x -4 = 6x + 4

6 * 7 = 42

42 + 4 = 46

Answer 2

The linear expression should be 6x + 4.

And, the perimeter is 46.

Given that,

A rectangle has side lengths (x + 4) feet and (2x - 2) feet.

Based on the above information, the calculation is as follows:

(x +4) + (x +4) = 2x +8

(2x -2) + (2x-2) = 4x -4        

Now

2x+8 +4x -4

= 6x + 4

The perimeter should be

= 6(7) + 4

= 42 + 4

= 46

A square garden with side length of 50 has a square shaped fountain display with length of 12 feet at the exact center of garden find the area of the garden

Answers

Answer:

The area of the garden is [tex]2356\ ft^2[/tex]

Step-by-step explanation:

Area of a Square

Given a square of a side length of x, the area is calculated as:

[tex]A = x^2[/tex]

There is a square garden area of a side length of x=50 feet. The area is:

[tex]A_1=50^2=2500\ ft^2[/tex]

Inside of it, there is another square area for a fountain display of a side length of 12 feet. The area is:

[tex]A_2=12^2=144\ ft^2[/tex]

The area of the garden is the difference between A2 and A1:

[tex]A_g=A_2-A_1=2500\ ft^2-144\ ft^2[/tex]

[tex]A_g=2356\ ft^2[/tex]

Please helppp. Solve for x in the diagram below

Answers

Answer:

12

Step-by-step explanation:

The diagram shows a right angle, therefore (6x-2) + 20 = 90.

Find x

(6x - 2) + 20 = 90

6x - 2 = 70

6x = 72

x = 12

Confirmation

[6(12) - 2] + 20 = 90

The answer is [6(12)-2]+20=90

In a right triangle, one of the angles measures 29º. What is the measure of the
other angles in the triangle?
45° and 61°
90° and 42°
90° and 61°
90° and 51°

Answers

Answer:

90° and 61°

Step-by-step explanation:

Since it's a right angled triangle, I thought it was wrong since you said right angle.

180 - 29 = 151

There is always one right angle in a right angled triangle, which is 90°, so you just have to deduct 90° and 29° from 180° and you will find out the answer.

180 - 29 - 90 = 61°

Find the other endpoint of the line segment with the given endpoint and midpoint.
Endpoint: (-9,7), midpoint: (10, -3)

Answers

Answer:

endpoint is (29, -13)

Step-by-step explanation:

Formula for midpoint is [tex](\frac{x_{1} + x_{2} }{2} ,\frac{y_{1} + y_{2} }{2} )[/tex]

So, let [tex](x_{2} , y_{2} )[/tex] be the coordinates of the endpoint you are looking for.

[tex]x_{1} = -9[/tex]  and [tex]y_{1} = 7[/tex]

[tex](\frac{-9 + x_{2} }{2} , \frac{7 + y_{2} }{2} )[/tex] = (10, -3)

[tex]\frac{-9 + x_{2} }{2} = 10[/tex]           [tex]\frac{7 + y_{2} }{2} = -3[/tex]

-9 + [tex]x_{2}[/tex] = 20         7 + [tex]y_{2} = -6[/tex]

[tex]x_{2} = 29[/tex]                    [tex]y_{2} = -13[/tex]

endpoint is (29, -13)

two turkey burgers and a bottle of water cost $3.25. If three turkey burgers and a bottle of water cost $4.50,What is the cost of tw bottles of water?

Answers

Answer:

$1.50

Step-by-step explanation:

let b be the number of turkey burgers and w be the number of bottles of water.

[tex]2b + w = 3.25\\3b + w = 4.50[/tex]

becomes

[tex]3b + w = 4.50\\- (2b + w)=3.25[/tex]

[tex]b = 1.25[/tex]

substitute this into one of the original equations:

[tex]3b + w = 4.5\\3 * 1.25 + w = 4.5\\3.75 + w = 4.5\\w = 0.75[/tex]

two bottles of water equals 0.75 * 2 = 1.50
