Properties of numbers 7(x-3)=7x-21

1 answer:

4 0

This property is called the distributive property. It is when you distribute the number outside the parenthesis into the numbers and letters inside the parenthesis.

Example:

7(x-3) = 7x-21

10(x+5+8) = 10x+50+80 = 10x +130

be sure to simplify like terms as in the example above

10 ( x²+5x³+2x²) = 10x²+50x³+20x² = 30x²+50x³

answer: 30x²+50x³

hope this helps

As we know, the economy in the long run tends to equilibrium, where the the production level is fixed and equal to the potential of production of the economy. The initial reduction of prices incentives the consumption in the long run, stabilizing with the long run quantites in a minor level of prices.

Karolina [17]

Answer:

15 years

Explanation:

If you are constructing a portfolio to cover the education expenses of your child and you expect that he/she graduates from college in 15 years, then the time horizon of your portfolio should be 15 years since it should cover all the expenses until your child graduates. If you start a little earlier and expect your child to graduate in 20 years, the time horizon will be 20 years, or if you start a little later and expect your child to graduate in 10 year, then the time horizon is 10 years.
