For this case we have an equation of the form:

Where,

A: initial amount

b: decrease rate

t: time

In this case we have the following equation:

Where,

t: number of years

Rewriting for the number of months we have:

Where,

t: number of months

For 8 years (96 months) we have:

round to the nearest hundred dollar:

V (96) = $ 4050

**Answer:**

**Answer:**

Set the area equal to x2, solve for x, and then multiply the value of x by 4.

**Step-by-step explanation:**

Answer:

(4a - 9)(4a + 9)

Step-by-step explanation:

Every value in the equation has a square root

The square root of 16 is 4

The square root of a^2 is a

The square root of 81 is 9.

To factor you split the equation by the square roots. For 81, since the original value is negative, one of the roots must be negative so when you multiply it back out to the original, it stays the same.

You can check your answer this way too.

(4a -9)(4a + 9)

= 16a^2 + 36a - 36a - 81

= 16a^2 - 81

I hope this helps!
