The length and width of Jessica's kitchen table are 6 ft and 3 ft or 3ft and 6 ft.

According to the question,

We have the following information:

Jessica found that the perimeter of her kitchen table was 18 feet she found the area of her kitchen table to be 18 ft.²

Now, let's take the length of the table to x ft and the width of the table to be y ft.

So, we know that following formulas are used to find the perimeter and area of rectangle:

Perimeter = 2(length+width)

2(x+y) = 18 ...(1)

Area = length*width

xy = 18

x = 18/y

Putting this value of x in equation 1:

2(18/y+y) = 18

18/y + y = 9

([tex]y^{2}[/tex]+18) = 9y

[tex]y^{2}[/tex]-9y+18 = 0

[tex]y^{2}[/tex]-6y-3y+18 = 0

y(y-6)-3(y-6) = 0

(y-6)(y-3) = 0

y-6 = 0 and y-3 = 0

y = 6 ft and y = 3 ft

Now, putting this value of y in x = 18/y:

x = 18/6

x = 3 ft

x = 18/3

x = 6 ft

Hence, the length and width of Jessica's kitchen table are 6 ft and 3 ft or 3ft and 6 ft.

In relation to the angle L of the right triangle the sides are as follows:

A right angle triangle is a triangle that has one of its angles as 90 degrees.  The sides of a right angle triangle can be named according to the position of the angles in the right angle triangle.

The sides of a right triangle can also be solved by using Pythagoras's theorem or trigonometric ratios.

Let's identify the sides  j,  k, and I in relation to angle L in terms of opposite, adjacent, and hypotenuse.

Therefore,

The hypotenuse side is the longest side of a right triangle.

Answer:

-3

Step-by-step explanation:

x= -18 + 15 = -3

The value of angle z in the triangle illustrated is C. 131°.

It should be noted that the value of the total angles in a triangle is 180°. In this case, the other two angles are given as 97° and 34°.

The other angle will be:

= 180° - (97° + 34°)

= 180° - 131°

= 49°

Therefore, the value of the angle z will be:

= 180° - 49° (angle on a straight line)

= 131°

Therefore, the correct option is C.

Step-by-step explanation:

10. The coordinates of the point W on the y-axis that makes VW + XW a minimum which is on the straight line joining V and X is  W(0, 1)

A straight line is a line without a curve, and the equation of a straight line in mathematics is y = m·x + c

10. The given points are V(2, 3) and X(-2, -1)

The location of the point W is on the y-axis

The shortest distance between two points is a straight line.

When VW + XW is a minimum, W is on the straight line joining V and X, such that by the segment addition postulate, VX = VW + XW

The slope of the line joining V and X, m, is found as follows;'

[tex]m=\dfrac{-1- 3}{-2 - 2} =1[/tex]

The equation of the line in point and slope form is therefore;

y - 3 = 1 × (x - 2) = x - 2

y = x - 2 + 3 = x + 1

The equation of the line VW in the slope and intercept form, y = m·x + c  is y = x + 1

The y-intercept is therefore, c = 1

The x-coordinates of a point on the y-axis is x = 0

The x-coordinate of W is 0

The y-coordinate of the point W on the line VX is given by the y-intercept of the line VX

The y-intercept of the line VX = 1 = The y-coordinate of the point W

The coordinate point W so that VW + XW is a minimum is W = (0, 1)

The number of bricks for the width is 12 the number of bricks for the length is 25

The length would be 200 inches, the width would 96 inches

1. The perimeter of the garden bed is the perimeter of a rectangle

where L = 2x + 1

B = x

we have to put the values in the formula

2((2x + 1) + (x))

The distance between the points is 17

A pair of numbers that describe the position of a point on a coordinate plane by using the horizontal and vertical distances from the two reference axes are defined as coordinates. The x- and y-values are commonly represented by (x,y).

Given that

Points G (-5,-8) and H (3,7) are plotted on a coordinate grid

We have to find the distance between points G and H

The formula for calculating the distance between two points is given by

= √((3-(-5))2 + (7-(-8)2)

= √((3+5)2 + (7+8)2)

= √((8)2 + (15)2)

= √(64 + 225)

Answer:

y = 15

Step-by-step explanation:

the triangle has congruent base angles of 50°

This means the triangle is isosceles with the 2 legs being congruent, so

3y - 10 = y + 20 ( subtract y from both sides )

2y - 10 = 20 ( add 10 to both sides )

2y = 30 ( divide both sides by 2 )

y = 15

The expenditure of the man in percent is 40%   and his savings is  Rs16200  .

In the question ,

it is given that ,

amount earned by the man = Rs 27000

amount spend by the man = Rs 10800

So , the expenditure in percent can be calculated using the formula ,

we get ,

= (expenditure)/(total earning)  × 100

= 10800/27000 × 100

= 0.4 × 100

= 40%

the savings = earning - expenditure

savings = 27000 - 10800

= 16200

Therefore , The expenditure of the man in percent is 40%   and his savings is  Rs16200  .

Applying the midsegment theorem:

a. x = 17; y = 2

b. Length of DF is: 20 units.

According to the midsegment theorem:

Length of GH = half the length of EF

Given the following:

GH = 1/2(EF)

Substitute:

x - 3 = 1/2(28)

x - 3 = 14

x - 3 + 3 = 14 + 3

x = 17

DH = HF

DH = y + 8

HF = x - 7

Therefore:

y + 8 = x - 7

Plug in the value of x

y + 8 = 17 - 7

y + 8 = 10

y = 10 - 8

y = 2

Length of DF = y + 8 + x - 7

Plug in the values of x and y:

Length of DF = 2 + 8 + 17 - 7

Answer:

Question 1: We need to know whether Angles P and N are congruent or not.

Question 2: Cannot be proven congruent

Question 3: AAS Congruence Theorem

Question 4: ASA Congruence Postulate

Step-by-step explanation:

Background info: The information (congruence lines on sides and angles) is read counterclockwise (starting from the very left to right).

Question 1: In order to prove the triangles congruent with the AAS, we need two pairs of congruent angles and one pair of congruent sides. We still need one more pair of congruent angles. Since the triangle is read counterclockwise, the angle to the left of the current congruent angle given needs to be given to us. This is angles P and N.

Question 2: For this answer, the triangles cannot be proven congruent because we are only given three congruent angle pairs. This means that it should be the "AAA" Theorem, however, it doesn's exist due to the fact that the triangles could still be two different sizes despite the fact that the angles are the same. In order to prove this congruent, we would need info on congruent sides.

Question 3: Reading the triangle left to right, we see a congruent angle pair (A), another congruent angle pair (A), and a congruent side pair (S). Putting this together, we get AAS.

Question 4: Reading the triangle left to right, we see an angle pair (A), a side pair (S), and an angle pair (A). Putting this together, we get ASA.
