Question

Помогите пожалуйста! ​

Answer 1

Ответ:

Объяснение:

(11x)/(5+y)

а) -5-y=-(5+y)

(11x)/((5+y)=(11x·(-1))/((5+y)·(-1))=(-11x)/(-5-y)

б) 15ay+3y²a=3ay(5+y)

(11x)/((5+y)=(11x·3ay)/((5+y)·3ay)=(33axy)/(15ay+3y²a)

в) 25-y²=(5-y)(5+y)

(11x)/((5+y)=(11x(5-y))/((5+y)(5-y))=(55x-11xy)/(25-y²)
