The solutions are
Step-by-step explanation:
To factor this cubic polynomial you must:
- Group the polynomial into two sections
- Factor out -9 from
- Factor out from
- Factor out common term
- Factor
- Using the Zero Factor Theorem: = 0 if and only if = 0 or = 0
The solutions are
Answer:
Option 1) 10 sides
Step-by-step explanation:
We are given a regular polygon. The sum of interior angles measure upto 1440 degrees.
Since it is a regular polygon, it satisfies the following properties:
- All the sides are equal.
- All interior angle have same measure.
Let the regular polygon have n sides.
Then, the sum of interior angle is given by:
Putting the values, we get,
Thus, there are 10 sides. The regular polygon is a regular decagon.
Answer:
Step-by-step explanation:
7x-11=4x+4(being vertically opposite angles)
7x-4x=4+11
3x=15
x=15/3
x=5
angle 2+angle1=180 degree(being straight line)
7x-11+angle 1=180
7*5-11+angle 1=180
35-11+angle1=180
24+angle 1=180
angle 1=180-24
angle 1=156 degree
Length = l = 3x
Width = w = 2x
P = 2l + 2w
P = 2(3x) + 2(2x)
530 = 6x + 4x
530 = 10x
53 = x
Length = 3x = 3(53) = 318 / 2 sides = 159
<span>Width = 2x = 2(53) = 212/ 2 sides = 106
the length of the lot is 159 yards
the width of the lot is 106 yards</span>
It would be x=3.50 because 8 divided by 4 is 2 and 14 divided by 4 is 3.5
