[$174 x 2]  + [$522 x 5] + [$870 x 10]=$348  + $2,610 + $8,700 ==$11,658 - amount of money he had at first.  

If you search this up, it would not come up. This is easy to do with the quadratic formula anyway. I do not need the answer. I think it is fun to give out question. If you were wondering, the quadratic formula is (-b+-sqrt(b²-4ac))/2a

T=2-dollar notes,   F=5-dollar notes,  N=10-dollar notes

1/3 = T / F............................(1)

3/5 = F / N...........................(2)

2T + 1/6[5F] = 783..............(3), solve for T, F, N

T = 174 - number of 2-dollar notes at first

F = 522 - number of 5-dollar notes at first

N=870  - number of 10-dollar notes at first.

$174 + $522 + $870 = $1,566.00 - Total amount he had at first.

only 37

x = 0

x = 1/8 (-5 - 3 sqrt(17))

x = 1/8 (3 sqrt(17) - 5)

Sum = 0 + 1/8 (-5 - 3 sqrt(17)) + 1/8 (3 sqrt(17) - 5)= - 5/4 = - 1.25

Same as before.

Lol, such a do-gooder and cheater enabler

Use the quadratic formula to simplify 2x² + 5x - 37 / 4.  

Is the whole thing over 4, or only the 37 ?  

history is just trying to cheat at homework again.

We can factor the equation as 4x(x2+45​x−2)=0. The first factor, 4x, never equals 0, so the only way the equation is true is if x2+45​x−2=0. By the quadratic formula, the roots of this equation are

[x = \frac{-5 \pm \sqrt{25 + 16}}{2} = -\frac{5 \pm 7}{2}.]The sum of the roots is then 2−5−5+7+7​ = 1.0​.

lcm(1 to 99) is NOT 99! In fact it is:  2^6 * 3^4 * 5^2 * 7^2 * 11 * 13 * 17 * 19 * 23 * 29 * 31 * 37 * 41 * 43 * 47 * 53 * 59 * 61 * 67 * 71 * 73 * 79 * 83 * 89 * 97

HOMEWORK CHEATER ALERT!!!! 🚨🚨🚨🚨🚨🚨

What's his brainly username?

I still wonder when this website turned from a math website to an insulting website. 

This, in fact, is not my blog. This link is actually something I came across scrolling around web2.0calc.com. I read most of it, and thought it was a good point for this website. 

Really? I did not know that. 

I think you know what they meant
