Factorise (x-y)^2-(x-y)^3=?

bogdanovich [222]

Answer:

$\left(x-y\right)^2\left(1-x+y\right)$

Step-by-step explanation:

You factor out the common term first.

You should get the equation below.

$\left(x-y\right)^2\left(1-\left(x-y\right)\right)$

then you get rid of the negative inside $\left(1-\left(x-y\right)\right)$

and will be simplified to this.

$\left(x-y\right)^2\left(1-x+y\right)$

Anon25 [30]

Answer: A. $16.13

Step-by-step explanation:

Total students = 82+74+96+99 =351

Sum of earnings of 82 seniors = $26.75 x 82= $2193.5

Sum of earnings of 74 juniors = $12.25 x 74 = $906.5

Sum of earnings of 96 sophomores = $15.50 x 96 = $1488

Sum of earnings of 99 freshmen = $10.85 x 99 = $1074.15

Total earnings = $2193.5 + $906.5+ $1488 +$1074.15

= $5662.15

(Total earnings) ÷ (Total students )

= $5662.15÷ 351

= $16.13
