Question

ce am incercuit acolo plssss​

Answer 1

la 25)b) am pus ca ambele valori sunt 2

2*2+3*2+2*2=14

26)(x+1)*(x+2)+(x+2)*(x+3)=50

(x+2)(x+1+x+3)=50

(x+2)(2x+4)=50

(x+2)(x+2)

x+2=5

x=5-2

x=3

la27)ab6+3ab+b9a=1173

100a+10b+6+300+100+b+100b+90+a=1173

111a+111b+396=1173

111a+111b=1173-396

111(a+b)=777

a+b=777:111

a+b=7

sper ca te am ajutat
