Rewrite exponential expressions

Mathematics
1 answer:
Dahasolnce [82]2 years ago
8 0

Answer:

A = 48

Step-by-step explanation:

In this equation, we can factor out the expression (\frac{1}{7} )^x. If we do so, the expression becomes:

(\frac{1}{7})^x((\frac{1}{7})^{-2} - 1)

We can simplify to get:

(\frac{1}{7} )^x(49 - 1)

and get:

48*(\frac{1}{7})^x

Therefore, A = 48

An even integer can be represented by the expression 2n, where n is any integer. Find three consecutive even integers that have
Setler79 [48]

As consecutive odd numbers differ by two (example: 3, 5, 7), the first odd number can be expressed as 2n + 1, the next can be found by adding two to the first to get 2n + 1 + 2 which simplifies to 2n + 3. Finally the expression for the third consecutive odd integer can be found by adding two to the previous, 2n + 3, to get 2n + 5. Adding these three together and setting them equal to your sum gets the equation

2n + 1 + 2n + 3 + 2n + 5 = 63

Combine like terms and solve For n.

Once you have n, you must substitute it back into your three expressions (2n + 1, 2n + 3, 2n + 5) to find the three odd integers.

Hope this helps :)
