Using CPhill's answer:

a = -d

but d is a positive integer, so minimum value of d is 1;

so maximum value of a = -d <-- so a = -1

Max used the common denominator x + 3 as follows:

3/1 - [2x + 3 /x + 3]   Use the common denominator of x + 3 and multiply it by 3:

3[x + 3] - [2x + 3] /[x + 3]

[3x + 9]   [2x + 3]

_____  _  _____

[x + 3]       [x + 3]

In order to prove algabraically that $\frac{0.5656...}{0.12424...}=\frac{560}{123}$, let's try to convert the interminable decimals to fractions.

I'll start with $0.5656...$

1. Set the Repeating Decimal equal to a Variable!

This is a farily simple step. $0.\overline{56}=x$. Now, you're good to go!

2. Multiply Both Sides by 10 such until the Repeating Portion is the Whole Number

In this case, if I multiply both sides by 100, which is 10^2, then the repeating portion will be to the left of the decimal point.

$56.\overline{56}=100x$

3. Subtract your 2 Equations.

4. Solve for x

Great! Now, let's convert the next one.

$0.1\overline{24}=y$

Now, multiply by multiples of ten to get the repeating portion to the left until the repeating part lines up.

$12.4\overline{24}=100y$

Now, subtract the two equations.

Now, solve for y.

Now, let's calculate what x/y is.

Therefore, we have proven algabraically that $\frac{560}{123}=\frac{0.\overline{56}}{0.1\overline{24}}$

 0.565656... / 0.124242424.....   Multiply both top and bottom by 990.

[990 x 0.56565656.... / 990 x 0.124242424.....] =560/123

This formula given by W/A in the above link of Melody will sum up any number of terms of B above:

So, the sum of the first 100 terms of B above will be:

1/12 n (n + 1) (n + 2) (3n + 5)=1/12[100 x 101 x 102 x 305] =26,184,250.

Wht is the answer to the other questions

B ) 1.2^2 + 2.3^2 + 3.4^2 + ......

This is what Wolfram alpha has to say about B

(I'm still thinking about it)

What would the part b be?

Carelessly transposing numbers is such a frustrating habit. I have stared at many problems for prolonged periods of time without realizing such error. 

"Express your answer as a decimal to the nearest tenth."

$\sqrt{52}=2\sqrt{13}\approx7.2\text{units}^2$

By its geometric definition, a segment is a portion of a line that is bounded between two endpoints. There are intersections at point A and point B, and there are intersection everywhere in between. Therefore, "the set of point A and point B and all the points between point A and B" is the most correct answer.

For future reference, there are $5280ft=1mi$

For area, though, these quantities are squared, so $27878400ft^2=1mi^2$

$144ft^2*\frac{1mi^2}{2787400ft^2}\approx5.17*10^{-6}mi^2$

Square both sides to get v² = 2gh

Divide both sides by 2g to get h = v²/(2g). This is your maximum height.

√52  = √  [ 4 * 13 ]  =  √ 4 *√ 13  =  2√13

Haha too much nonsence 

Thank you guest!

=5.165×10^-6 mi^2 (square miles)

I don't need steps Thanks!
