Question

Stiind ca a+b=250 c=50 calculati

AxC+BxC=
(A+B): C=
A+B+C : 25=
2(A+B)+ Cx2=

Answer 1

A+B=250

C=50

AxC+BxC=(A+B)xC=250x50=12500

(A+B):C=250:50=5

A+B+C:25=250+50:25=250+2=252

2(A+B)+Cx2=2x250+50x2=500+100=600

Answer 2

Răspuns:

Explicație pas cu pas:

a + b = 250   si   c = 50

a × c + b × c = c × ( a + b ) = 50 × 250 = 12 500

( a + b ) : c = 250 : 50 = 5

a + b + c : 25 = 250 + 50 : 25 = 250 + 2 = 252

2 × ( a + b ) + c × 2 = 2 × 250 + 50 × 2 = 500 + 100 = 600
