Yea u have to do that the most effective is the 10 bc penny is right
8•20=q. Multiply the number of piles by the number of quarters in each pile: 8•20=160, there were 160 quarters. Now to find how much they made multiply the number of quarters by how much 1 quarter is: 160•.25=40 they made $40 :)
F(x)= (x+13)(x-2) in expanded form, it would be x^2+11x-26
The correct option is C. In Nuclear reactions, two nuclear particles collide to produce products that are different from the reactants. During nuclear reaction, a lot of processes take place. In nuclear reactions, the total energy is conserved. Thus, the missing rest mass energy can be accounted for by using the Einstein's formular to find mass - energy equivalence.
