to Dragonlance: no no no, I don't play farmville

25% the money that I get from successfully completing attacks goes to the Troop Support Squad, where they buy the good food, weapons, armor, gernades, etc. for all our troops to be supplied with

so actually the money from attacks is the way I feed my troops

wow

maths been taking it easy going gold on me this year

ENGLISH is the one who took me to their Torture Lab

appearently I have to do a 'Passion Project' about making a "passionate" product

and so far, making a RPG game is complicating as scientific notation

Inequality means not equal so 3>2 is an inequality. anything that uses < or> is an inequality

The five-number summary of a set of data:

 minimum, first-quartile score, median (which is the second-quartile score), third-quartile score, maximum

there is no exact decimal but the closest would be .66666666 repeating forever

9d - 2d = 7d

18-18 = 0

The equation becomes:  7d  =  0

Divide both sides by 7:      d  =  0

Yes; the answer is 0.

it is like this 8/7=1.5

$$\mathrm{ERROR}..{\mathtt{21}}$$

ab + 4a +2b + 8         =

a(b + 4) + 2(b + 4)     =   [take out the common factor, (b + 4), and write back what is left, (a + 2)

(b + 4) ( a + 2)

x2 −2x − 35 = 0    let's factor this....

(x - 7) ( x + 5) = 0    now.....set each factor to 0

x  - 7 =  0                              x + 5  = 0

add 7 to both sides              subtract 5 from both sides

x = 7                                    x  =  -5

And there are the two solutions, isbella  !!!

Thank you everyone....Maths been hittin me hard this year

In the last two, we are just raising the sine function to some power(s).......the first one indicates that we are taking the sine inverse [i.e., finding the angle associated with the value of the sine for that angle ].....so it's the one that is different....!!!

x - 8y = -56      let's put it in this form.....

8y = x + 56      divide both sides by 8

y = (1/8)x + 7

So...the slope is (1/8)   and the y intercept  is just (0, 7)....just as Dragonlance found  !!!!

x^( )   *  x^6  = x^9      divide both sides by x^6   =

x^( )  =  x^9 / x^6   

x^( )   =  x^3        .....therefore......the "blank" exponent  must equal "3"

3x^2 * 3x^2 =

3 * 3 * x^2 * x*2        =

9x^4      .....remember the rule......a*m * a^n   =  a^(m + n).....!!!

(-5)^2  == (-1)*(5)*(-1)*(5) =  (-5)*(-5)  = 25

But

-5^2  = -1(5)^2  = -1*(5)*(5)  = -25  !!!!

This is a common error...in the first case the exponent applies to the "understood" -1 in front of the "5"....in the second case, the exponent only applies to the 5 itself, not to the "understood" -1....be careful, here  !!!

The absolute value of a negative number is its positive value:  |-4.236|  =  4.236
