Answer:c
Step-by-step explanation:
Answer:
D similar by AA
Step-by-step explanation:
<em>L</em><em> </em>B = <em>L</em><em> </em>D ( right angle)
<em>L</em><em> </em>BCA = <em>L</em><em> </em>DCE (push back angle)
(2x+10)(2x+10) use FOIL to solve (First, Outer, Inner, Last)
4x^2+20x+20x+100
Combine like terms
4x^2+40x+100
Answer:
The values of x and y is given by the equation
.
Step-by-step explanation:
Given : Five whole numbers are written in order 4 6 x y 10
, the mean and median of the five numbers are the same.
To find : The values of x and y ?
Solution :
Observations 4, 6, x, y, 10.
Mean is summation of observation divided by number of observation.
i.e. 


Median is middle term of observations.
Median of odd terms
term

term
The mean and median of the five numbers are the same.
i.e. 


The values of x and y is given by the equation
