Me! you have a minimum time of 20 minutes. simplify: (x + y)(x + y) a. x2 + 2xy + y2 b. x2 + y2 c. 2x2 + 2xy + 2y2 d. x2 – y which one is the answer?

(A)

Step-by-step explanation:

The given equation is :

=

We need to simplify the given equation, so

Using the identity,

, we have

=x^{2}+2xy+y^{2}[/tex]

Which is the required simplified form of the given equation.

Hence, option A is correct.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
