Aida applied the distributive property to write the equivalent expressions below. 15 + 21 = 3 (4 + 8) What is Aida’s error? Aida used 3 as the factor, which is not common to 15 and 21. Aida did not correctly divide by the common factor to get (4 + 8). Aida did not apply the correct operations to the expressions. Aida wrote two expressions that are not equivalent.

entering that problem on the tube might get you an answer

1260=3*6*7*10=3^2*2^2*7*5 perfect cude = 3^3*2^

step-by-step explanation:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
