the angles of quadilateral are, x,2x,3x and 4x find the value of x
Answer:
the angle sum of quadrilateral is 360 degree
x+2x+3x+4x = 360
10x=360
x= 360/10
x= 36
1 angle= 36
2 angle= 2*36=72
3 angle =3*36=108
4 angle= 4*36= 144

Given the roots of 4 and -2 find the equations of the quadratic.
4 points
Answer:
p(x) = x² - 2x -8
Step-by-step explanation:
We need to find the quadratic equation with roots 4 and -2 , we know that if a and ß are the roots of equⁿ , then the polynomial is ,
[tex]\implies p(x) =k[ x^2-(\alpha + \beta)x+\alpha\beta] [/tex]
Where k is constant . Substitute respective values ,
=> p(x) = k [ x² - ( a + ß )x + aß ]
=> p(x) = k [ x² - ( 4-2) x + (4)(-2) ]
=> p(x) = k [ x² -2x - 8 ]
If k = 1 ,
=> p(x) = x² - 2x - 8

10. The perimeter of a regular nonagon is 162 inches. The apothem is 97.8 inches. Find the area.
Answer:
The area of the regular nonagon is 7921.8 square inches.
Step-by-step explanation:
Geometrically speaking, the area of a regular polygon is determined by following area formula:
[tex]A = \frac{p\cdot a}{2}[/tex] (1)
Where:
[tex]A[/tex] - Area of the regular polygon, in square inches.
[tex]p[/tex] - Perimeter, in inches.
[tex]a[/tex] - Apothem, in inches.
If we know that [tex]p = 162\,in[/tex] and [tex]a = 97.8\,in[/tex], then the area of the regular nonagon is:
[tex]A = 7921.8\,in^{2}[/tex]
The area of the regular nonagon is 7921.8 square inches.

6(3+8)
6.3 + 6.8

Answer:
6(3+8)
Step-by-step explanation:
6(3+8)= 6×3+6×8=18+48
this is the given value of A
The correct expressions for total area = 6x3 + 6x8 or 6(3+8)
What is rectangle?Rectangles are four-sided polygons with all internal angles equal to 90 degrees. At each corner or vertex, two sides meet at right angles. The rectangle differs from a square in that its opposite sides are equal in length.
In the given figure,
Area of one room = 18 square feet
Area of second room = 48 square feet
Now since we can see that,
the width of both rooms is same,
therefore,
we have 6 as common factor of 18 and 48
As, 18 = 6x3
48 = 6x8
Total are of the given figure = 18 + 48
Since we know that,
Area of rectangle = length x width
Therefore,
area of both rooms = 18 + 48
= 6x3 + 6x8
= 6(3+8)
Hence,
The rooms total area of both rooms = 6x3 + 6x8 or 6(3+8)

How do you find the y-intercept of a line if you have the slope and a point? Describe the steps in order.
Using the "slope-intercept" form of the line's equation (y = mx + b), you solve for b (which is the y-intercept you're looking for). Substitute the known slope for m, and substitute the known point's coordinates for x and y, respectively, in the slope-intercept equation. That will let you find b.
Hope that helps!!!!
Answer:
it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis.

Answer:
D=121
Step-by-step explanation:
First fin the angles on the inside using the outer angles. Always use 180 as your main number to subtract from. 180-131 = 49 180-108= 72 72+49=121
180-121=59 180-59=121
Or an easier way is to see if your outer angles equal up to 360
So 131+108=239
360-239=121
And there's your solution.

Victor wants to buy fertilizer for his yard. The yard is 45 feet by 55 feet. The direction on the bag of fertilizer say that one bag will cover 1,250 square feet. How many bags of fertilizer should Victor buy to be sure that he covers the entire yard? 2 SEE ANSWERS
Answer: 2 bags
Step-by-step explanation:
First find the area of the yard.
The area given the units would be:
= Length * Width
= 45 * 55
= 2,475 ft²
Victor needs enough fertilizer to cover 2,475ft² but each bag covers only 1,250 ft².
The number of bags needed is therefore:
= 2,475 / 1,250
= 1.98
= 2 bags
