9 plsss urgent va roooooooooooggg

Answer 1

Răspuns

PΔ=l+l+l = 10 + 14 + 8 =32 cm

Explicație pas cu pas:

a= 7+3x[2-27:(5x5+2:1)]

a= 7+3x[2-27:(25+2)]

a= 7+3x(2-27:27)

a= 7+3x(2-1)

a= 7+3

a=10

b= (5+5:5+2-2:2)x2

b= (5+1+2-1)x2

b= 7x2

b=14

c= [36-16:(25:5-12:3)]:5+4

c= [36-16:(5-4)]:5+4

c= (36-16:1):5+4

c= (36-16):5+4

c= 20:5+4

c= 4+4

c= 8

PΔ=l+l+l = 10 + 14 + 8 =32 cm
