Answer:

-6xy

Step-by-step explanation:

(2x-y)x(x-2y)-(x+2y)X(2x-y)

remove the parentheses

2x^2-4xy+xy-2y^2-(2x^2-xy+4xy-2y^2)

collect terms

2x^2-4xy+xy-2y^2-(2x^2+3xy-2y^2)

remove the parentheses

2x^2-4xy+xy-2y^2-2x^2-3xy+2y^2

remove the opposites, collect the terms to get -6xy

The sum of two numbers is 32. Five times the smaller number minus twice the larger number is 195.What are the numbers ?

Harlamova29_29 [7]

Answer:

37 and -5

Step-by-step explanation:

Le the numbers be x and y

Then we have equations:

x + y = 32
5x - 2y = 195

As per the first equation:

y = 32- x

Substitute in the second equation

5x - 2(32 - x) = 195
5x + 2x - 64 = 195
7x = 195 + 64
7x = 259
x = 259/7
x = 37

Then finding the value of y

y = 23 - 37 = -5
