This ellipse is centered at the origin. Find its equation. Vertices:(0,-6) and (0,6)
Foci:(0,-2) and (0,2)

180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

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.
