JKLM is a rectangle. if JL = 4x - 12 and MK = x, what is the value of x? what is the length of each diagonal?

Answers

Answer 1

Answer:

x = 4

The diagonals are both 4

Step-by-step explanation:

The fact that the two sides have no letter in common indicates that they are opposite each other or a diagonal. In this case the length is a diagonal. Diagonals in a rectangle are equal.

4x - 12 = x                      Add 12 to both sides

4x - 12 + 12 = x + 12      Subtract x from each side

4x - x = 12

3x = 12                           Divide by 3

3x/3 = 12/3

x = 4

One of the diagonals = 4 because it is x.

Find the area of a circle in feet with the radius being 3'.

Answers

Answer:

28.27 ft²

Step-by-step explanation:

[tex]A=\pi r^2[/tex] where [tex]r[/tex] is the radius

Plug in 3 for the radius

[tex]A=\pi (3)^2\\A=9\pi[/tex]

[tex]A=28.27[/tex] (approximate answer when rounded to the nearest hundredth)

Therefore, the area of the circle is 28.27 ft².

I hope this helps!

Answer:

exact area: 9 ft²

approximate area: 28.3 ft²

Step-by-step explanation:

An area cannot be in feet. It must be in a square unit such as square feet.

A = r²

A = ()(3 ft)²

A = 9 ft²

A = 9(3.14159) ft^2 = 28.3 ft²

Find the area of the circle, given the square has an area of 144 cm2 (leave your answer in terms of ).
A)
127 cm?
B)
2471 cm2
C)
3671 cm2
D)
7271 cm2

Answers

C is the answer to this question explanation: Area of square = 144 cm2, which means each side is √144 = 12 cm

Since the circle is inscribed in the square, the diameter is 12, so the radius is 6cm.

Area of circle = πr2 = π * 62 = 36π cm2, which is your answer :)

SOS PLEASE HELP write the equation for this line​

Answers

Answer:

Step-by-step explanation:

Line is passing through the points (3, 0) & (0, 3)

y-intercept (b) = 3

Slope of the line (m) = (3 - 0)/(0 - 3) = 3/(-3) = - 1

Now, required equation of line is given as:

2 (3x - 5) + 4 = -18


Solve for 20 Points

Answers

Answer:

x = -2

Step-by-step explanation:

2(3x - 5) + 4 = -18

Distribute the 2

6x - 10 + 4 = -18

6x - 6 = -18

Add 6 to both sides

6x = -12

Divide both sides by 6

x = -2

Check:

2(3x - 5) + 4 = -18

substitute x = -2 into the original equation

2(3(-2) - 5) + 4 = -18

2(-6 - 5) + 4 = -18

2(-11) + 4 = -18

-22 + 4 = -18

-18 = -18

So x = -2 is true.

Answer:

x=-2

Step-by-step explanation:

2(3x-5)+4=-18

We move all terms to the left:

2(3x-5)+4-(-18)=0

We add all the numbers together, and all the variables

2(3x-5)+22=0

We multiply parentheses

6x-10+22=0

We add all the numbers together, and all the variables

6x+12=0

We move all terms containing x to the left, all other terms to the right

6x=-12

x=-12/6

x=-2
