Hint 1. understanding mean square velocityopened hint the mean square velocity is given by (v2)avg=(∑v2)/n, where the sum is taken over all the molecules in the gas and n is the total number of molecules. if you take the central speed value of each bin as an estimate of the speed of all the molecules in that bin, this equation reduces to (v2)avg=∑binsnbinv2n, where the sum is now over the number of discrete bins and nbin is the number of molecules (or equivalently the percentage of molecules) in a particular bin.

Factor the polynomial, if possible. if the polynomial cannot be factored, write prime. 9n^3 + 27n^2 – 25n – 75

Will mark brainliest, , and rate to only chrislaurencelleenzo is making a scale drawing of the rectangle below. ~imageenzo says that he can draw an enlarged rectangle that is 16 centimeters by 13 centimeters. which explains whether enzo is correct? enzo is correct because he used a factor of 2 to enlarge the rectangle. enzo is correct because he doubled one dimension and added the two lengths to get the other dimension. enzo is not correct because the enlarged rectangle should be 16 centimeters by 5 centimeters. enzo is not correct because he did not multiply the length and width by the same factor.
