(2) 2b(a +302)
...... hope it's helpful
answer is 2b(b^2 + 3a^2)
number of pencils in one package = 3
number of pencils zayed has = 72
number of calculators zayed has = 24
since, he has to use all the pencils and calculators.
so packaging should be done in a way that no pencil or calculator is left out from packaging.
so to find how many pencils and calculators should be there in one package we must find the ratio of pencils to the number of calculators.
so, if the package contains 1 calculator then the package must contain 3 pencils.
hence, number of pencils in one package = 3
