Answer: x = 27
Step-by-step explanation:
x/3 - 11 = -2
Add 11 to each side
x/3 = 9
Multiply each side by 3
x = 27
x cannot equal 21.
21/3 - 11
21/3 = 7
7 - 11 = -4
-4 does not equal -2
Therefore, x cannot equal 21.
No other regular polygon can tessellate because of the angles of the corners of the polygons. In order to tessellate a plane, an integer number of faces have to be able to meet at a point. For regular polygons, that means that the angle of the corners of the polygon has to divide 360 degrees.
Answer:
L=10.326cm
P=31.30cm
Step-by-step explanation:
A=55=L*W
L=5+W
A = (5+W)(W) = 55
55=W^2 + 5W
0 = W^2 + 5W - 55
use quadratic formula
W = [-5 (+/-) sqrt(25-4(-55))]/2
W= 5.326 cm or W=-20.65, so W=5.326cm
L=5+5.326
=10.326cm
P=2W+2L
P=2(5.326) + 2(10.326)
=31.30 centimeters
120/100 is your fraction and 1.2 in a decimal
