Yes since the four sides are always parallel in a square <span />
Answer:
140, 60
Step-by-step explanation:
15x+5 + < CDB =180 line form an 180 angle
180-80-6x-6 = < CDB sum of angles in a triangle is 180
substitute < CDB from second to first
15x+5+180 -80-6x-6 =180
combine like terms
9x -81 =0
x=81/9=9
so angle YDC = 15*9+5 = 140 degrees
and angle DBC = 6*9+6= 60 degrees
m^2-2mn+n^2 m=-2
(-2)^2-2*-2*4+(4)^2
=>4+16+16
=>36
Hope this helps u...!!!
Answer:
The two consecutive integers are 6 and 8 or -8 and -6.
Step-by-step explanation:
The product of two consecutive even integers is 48, and we want to find the two integers.
We will let <em>x</em> represent the first even integer.
Then the consecutive even integer will be (<em>x</em> + 2).
Its product is 48. Therefore:

Solve for <em>x</em>. Since this is a quadratic, we should get one side to equal to 0. Expand:

Subtract 48 from both sides:

Factor:

Zero Product Property:

Solve for each case:

Therefore, our two consecutive integers are 6 and 8 or -8 and -6.
Answer:
0.0062
Step-by-step explanation:
Given that the mount of orange juice in a 500 ml can from a certain company is a random variable with a mean of 500 ml and a standard deviation of 2 ml.
As per central limit theorem sample mean follows normal here with mean = 500 ml and std error - 
Sample mean is N(500, 0.2)
Required probability
= probability that the sample mean is less than 499.5 ml
= 
Rounding off
0.0062
