Answer:

The amount of glass needed to make the lampshade is:

  166.27 square inches

Step-by-step explanation:

The base of the lampshade is a regular hexagon with a side length of 8 inches.

Estimate the amount of glass needed to make the lampshade.

Area of hexagon of side s= (3√3 s²)/ 2

 Here, s= 8 inches

Area= \dfrac{3\times \sqrt{3}\times 8\times 8 }{2}

       =166.27 square inches

Hence,  the amount of glass needed to make the lampshade is:

  166.27 square inches

Estimated is ; A ≈ 166.28

Because you must use the area of a hexagon to find the answer

You're welcome:)

Factor 26r3s + 52r5 – 39r2s4.
algol [13]

Answer:

13r²(2rs + 4r³ - 3s⁴)

Step-by-step explanation:

In equation 26r³s + 52r⁵ - 39r²s⁴;

The GCF of 26, 52, and 39 = 13

The GCF of r³, r⁵ and r² = r²

The GCF of s, (no "s"), and s⁴ = no "s" (Since one of the number doesn't have "s")

Now we can factor out 13r² from all three expressions;

26r³s + 52r⁵ - 39r²s⁴

=> <em>13r²(2rs) + 13r²(4r³) - 13r²(3s⁴)</em>

To factor it all together;

<u>13r²(2rs + 4r³ - 3s⁴)</u>

Hope this helps!

Solve for x and y. Geometry
Otrada [13]

Answer:

x =106.5

y = 73.5

Step-by-step explanation:

Angle x is 1/2 arc SPQ

x = 1/2(98+115)

x = 1/2(213)

x =106.5

We know that x+y = 180  since this is an inscribed quadrilateral in a circle

x+y=180

106.5 +y =180

Subtract 106.5 from each side

106.5-106.5 +y =180-106.5

y = 73.5

How do I solve this problem?
nexus9112 [7]
Subtract the second equation from the first equation.
x = -1
Plug -1 back in to either equation and solve for y.
3(-1) + y =-10
-3 + y = -10
Add 3 to both sides
y = -7
CHECK
3(-1) -7 = -10
2(-1) -7 = -9
(-1, -7)
