Question

СРОЧНО ПОЖАЛУЙСТО ПОМОГИТЕ!!!!​

Answer 1

Ответ:

Объяснение:

1) x=-12

x²/(3x-18) +36/(18-3x)=x²/(3x-18) -36/(3x-18)=(x²-36)/(3x-18)=((x-6)(x+6))/(3(x-6))=(x+6)/3=(-12+6)/3=-6/3=-2

2) c=199, k=0,2=1/5

c²/(c-5k) -(25k²-10ck)/(5k-c)=c²/(c-5k) +(25k²-10ck)/(c-5k)=(25k²-10ck+c²)/(c-5k)=(5k-c)²/(c-5k)=-(5k-c)²/(5k-c)=-(5k-c)=c-5k=199 -5·1/5=199-1=198
