Answer:
-10x (1 - y)
Step-by-step explanation:
Given :-
Side 1 = (2x + 5xy)
Side 2 = (-7x - 10xy)
To Find :-
Perimeter
Formula :-
Perimeter (rectangle) = 2 (Side 1 + Side 2)
Solving :-
Perimeter = 2 (2x + 5xy - 7x - 10xy)
= 2 (-5x - 5xy)
= -10x (1 - y) => [Solution]
Step-by-step explanation:
perimeter: 2 (2x+ 5xy+(-7x-10xy)
= 2(2x+5xy-7x-10xy)
= 4x+10xy-14x-20xy
= -10x-10xy
= -10x(1+y).
Answer: -10x(1+y)
