Answer:
2x² + 4x
Step-by-step explanation:
= (3 - 1)(x + 2)(x)
= (2)(x + 2)(x)
= (2x + 4)(x)
= 2x² +4x

The initial amount was 200 dollars.
If you sub in 0, you get the amount at 0 months.
Rate of change is the slope. You are losing -75 a month, which is the rate of change.
To turn
into a fraction you should do such steps:
1 step. Set up an equation by representing the repeating decimal with a variable. Using your example, you will let x represent the repeating decimal 0.(6), so you have x=0.666... .
2 step. Identify how many digits are in the repeating pattern, or n digits. Multiply both sides of the equation from Step 1 by
to create a new equation. Again, using your example, you see that the repeating pattern consists of just one digit: 6. Now multiply both sides of the equation by
. Thus, you have
or
.
3 step. Subtract the equation in Step 1 from the equation in Step 2. Notice that when we subtract these equations, our repeating pattern drops off. Therefore,
.
4 step. You now have an equation that you can solve for x and simplify as much as possible, using x as a fraction:
. If you divide both sides by 9, you get
. When simplified, you get that
.
Answer:
.
The answer should be B because 4*4=16 so 60 -16 a day
