Expand: \((a-4)(b-4) = ab - 4a - 4b + 16 = ab - 4(a+b) + 16 \)

By Vieta's formula, we know that \(ab = -{5 \over 7 }\) and \(a+b = -{1 \over 7}\)

Now, plugging this in, we get: \(-{5 \over 7} -4(-{1 \over 7})+16 = {-{5 \over 7}} + { 4 \over 7}+16 = \color{brown}\boxed{15{ 6 \over 7 }}\)

3/1 - 13/5 = 15/5 - 13/5 = 2/5

Let n be the smallest and  n + 4 the largest.....and we  have that,,,,,

n >  (3/4)(n + 4)

n >  (3/4)n + 3

n - (3/4)n > 3

(1/4)n > 3       multiply both sides by 4

n > 12

So  n =  13

im sorry but its wrong

Does anyone know how this is written in exponential form?

Hello vxnessa!

When x is equal to 4, y = 4.

Daniel & Celvin total toys = 323

Daniel's toys = 7/10 of Celvin's toys

[D = 7/10 * C] - (1)

According to question; D + C = 323

(D + C) = 323

(7C/10 + C) = 323 (from (1))

(7C + 10C) = 3230 => C = (3230/17)

Calvin's toys = 190

Daniel's toys = (323 - 190) => 133

Difference with the toys both have => (190 - 133) = 57

Hey there is something missing in your problem!!!

5+4+87654345+87392+X = what????

Wait @hipie what happened?

66+66=132

I think both of you guys messed up :)

This honestly should be posted in the sticky topics (in my opinion

Im too lazy to learn LaTex

$\mathrm{Omg \ it \ actually \ works}$

Or you can use "\mathrm{}", for example: \(\mathrm{Factor}\:4x^4-12x^3+8x^2+12x-1\)

You see how the word "Factor" is in normal font...

You can do that!!!! 

Use can also use these ~ or \quad \qquad etc. 

Like this $you~can~use~space~easily$

\(\prod _{n=3}^5n^{\frac{1}{2\pi }}\)

\(a_3=3^{\frac{1}{2\pi }} \)

\(a_4=4^{\frac{1}{2\pi }}\)

\(a_5=5^{\frac{1}{2\pi }}\)

\(3^{\frac{1}{2\pi }}\cdot \:4^{\frac{1}{2\pi }}\cdot \:5^{\frac{1}{2\pi }}\)

\(=60^{\frac{1}{2\pi }}\)

Well, I did everything I can, I don't think I can solve this one then. Maybe ask someone or a mod !

How was it not helpful, what else do you need? 

Very helpful!!

wow thanks! I really never heard of it!

bro.

That's cool I didn't know that!!

Thanks, guest!! Saves a lot of time!!!

Well 1/12 of an hour is 5 minutes. So he called the police at 3:22 P.M. 

And 3/10 of an hour is 18 minutes. So They arrested him at 5:40 P.M.

A little late for donuts in my opinion, Probably why they caught him.
