Answer:
4,7025 (kJ).
Step-by-step explanation:
1) according to the condition: m=25 gr.; t₂=90; t₁=45; c=4.18 J/(g°C);
2) the formula of required heat is
Q=c*m*(t₂- t₁);
3) according to the formula of heat:
Q=4.18*25*45=4702.5 (J).
The question is -x/3 = 2 which is 1/3x=2
multiply both sides by 3, and you'll get x = 6

Answer:
28
I'm not fully sure
Step-by-step explanation:
(m^2-5m+9)^2
9^2(9x2)= 18
m^2-5m+18
2x-5= 10( need to find a way to remove the m)
10+18=28
the way I solved it is confusing
