Answer:

Step-by-step explanation:
Given;
p(x) = x³ + x²- 20x + 24
factor of p(x) = x-3
Apply long division method;
x² + 4x - 8
------------------------------
x - 3 √ x³ + x²- 20x + 24
-( x³ - 3x²)
-------------------------------
4x² - 20x + 24
-(4x² -12x )
-------------------------------
-8x + 24
- (-8x + 24)
-----------------------------------------

A polygon is any figure sided with three sides and above such that triangle (3) is the smallest polygon. A nonagon is a polygon with 9 sides. To get the sum of interior angles of a polygon we use the formula;
(n-2) 180 or (n-4)90 where n is the number of sides.
Therefore, for a nonagon the sum of interior angles = (9-2) 180 = 1260 degrees
If we add all the angles we should get 1260, considering the remaining angles to be each x
Thus 138+154 +145 +132 +128 +147 +130 + x +x =1260
= 974 + 2x = 1260
= 2x = 286
= 143
therefore, each of the other angles was 143
Answer:
58 %
Step-by-step explanation:
So 18 % of the beads are green and 40 are purple add those and you get 58
Answer:
1)
A)
We must use the formula b x h/2 12 x 8/2 = 48
A=48
B)
We must use the formula 1/2a root c squared - a squared
Solving and substituing will get you 35.78
2)
A)
We must divide 81 by 2 to get 9. Since this is a square, all sides will be 9. Then, we must add 9 four times to get 36 cm as our perimeter
B) If we draw the square with a diagonal line, we can understand that the diagonal line (hypotenus) is s root 2.
3) The formula for this area of a triangle is h x b/2. We must substitute the numbers to get our answer:
h x b /2 = 10 x 20/2 = 200/2 = 100
AREA IS 100cm squared
