Answer:
As space expanded, the universe cooled and matter formed
Explanation:
Amount of time=2.5 hoursamount of time after speed increase=2 hourslet x=the initial speedlet t=the amount of hourslet y=the new speed let z=distance therefore xt=zyt=zplugging everything in,x(2.5)=zy(2)=zusing substitution y=20+x2.5x=z(20+x)(2)=z40+2x.5x=40x=80y=x+20y=100
The laws are stated: Like poles repel each other. Unlike poles attract each other.

Answer:
0.
Explanation:
If you do a=2 and b=2, then 2-2=0.
Environment is something very important today, because it is becoming more and more polluted. People do harm without being aware that they destroy the world. People just want more and more money and more and more destruction, which is definitely the cause, yet people do not know the effect that it can cause. Without explaining the effect that pollution can cause, today's environment cannot be explained. Shortly, by being greedy (the cause), we destroy our habitat (the effect)
Answer
\((y + 3) (y^{2} - 3 y + 9) V)
Explanation
Explanation
Detail ste
Apply \(a^3\pm b^3=(a\pm b)(a^2\ mp ab+b^2)V : \((y + 3) (y^[2} - y \times 3 + 3^{2}) V
Multiply the monomials: \((y + 3) (y^{2} -3y + 3^{23) V
Calculate the power: \((y + 3) (y^{2} - 3 y + 9) V
