Answer:

x=+46

Step-by-step explanation:

2x+4=4x-88

We move all terms to the left:

2x+4-(4x-88)=0

We get rid of parentheses

2x-4x+88+4=0

We add all the numbers together, and all the variables

-2x+92=0

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

-2x=-92

x=-92/-2

x=+46

Area  of circle  = pi r^2 = 78.54
r^2 = 78.54 / pi = 25
r = 5 inches

Each line from centre of the circle to a point on the hexagon = 5 ins

so  consider one of the 6 congruent triangles formed from these lines:-
Vertex angle = 60 degrees

sin 30  = 0.5s / 5    (where  s = one side of the hexagon).
0.5s = 5*0.5 = 2.5
s = 2.5 / 0.5 =  5 

So the perimeter of the hexagon is 6*5  = 30 inches

The area of the circle is 64pie cm. What is the radius in cm?
Vinil7 [7]

Answer: 8 centimeters

Step-by-step explanation: To find the radius of the circle, remember that the formula for the area of a circle is πr² and since we're given that the area of our circle is 64π, we can set up the equation 64π = πr².

To solve for <em>r</em>, we first divide both sides of the equation by π.

On the left side, the π's cancel and we're left with 64 and on the right side, the π's cancel and we're left with r².

So we have 64 = r².

Next, we take the square root of both sides to get 8 = r.

So the radius of our circle is 8 centimeters.

Find the Slope:
AveGali [126]

Answer:

4) slope= 0

5) slope =  -  \frac{1}{7}

Step-by-step explanation:

\boxed{ slope = \frac{y _{2} - y_1 }{x_2 - x_1} }

4) Slope

=  \frac{10 - 10}{ - 10 - 3}

=  \frac{0}{ - 13}

= 0

The slope is zero as the line is a horizontal line (since both points have the same y-coordinate of 10).

5) Slope

=  \frac{5 - 4}{2 - 9}

=  \frac{1}{ - 7}

=  -  \frac{1}{7}

Since you have taken (x₁, y₁) to be (9, 4), the value of x₁ should be 9 instead of 2.
