7(2 2/3a - 5b)
(5x+12)+(-3x-1)
1/3(15a2)+27b)-3(a2-4)
Proszę o całe obliczenia
7(2 2/3a - 5b) = 7 (8/3a-5b) = 56/3a-35b
(5x+12)+(-3x-1)= 5x+12-3x-1=2x+11
1/3(15a^2)+27 = 5a^2+27
-3(a2-4) =-3a^2+12
pozdrawiam wroniaak :)
7(2 2/3a - 5b)=7(8/3a-5b)=18 2/3a-5b
(5x+12)+(-3x-1)=5x+12-3x-1=2x+11
1/3(15a2)+27b)-3(a2-4)=5a²+27b - 3a²+12=2a²+27b+12
