yes you can. divide by 2 and just keep going until you reach the most simplified answer

and, are you sure "ignoring" would make things vanish?

i, personally, don't think ignoring works. I try to ignore in many situations, but it just doesn't work. I clash instead of ignore.

but if that's what you want, then let it be

81m^2 - 3 = 46      add 3 to both sides

81m^2 = 49         divide both sides by 81

m^2 = 49 / 81      take the square root of both sides....remember...we have to take both roots  !!!!

m  = ± ( 7 / 9 )

that looks interesting Chris :)

thanks  ShadowBolt04

That is the BEST answer for this question  

z^2 + (11/8)z + c

Take 1/2 of 11/8   =  11/16......now......square it  =    121 / 256......   this is "c"

So we have

z^2 + (11/7)z + 121 / 256 =  

(z + 11/16) ^2

YES that is EXCELLENT  MG !!!    

If  Lila read "L" books, then 1/2 as many = (1/2)L...and Ryan read 5 more than this...

So, Ryan read  ..   (1/2)L + 5   ... books

Welcome GalaxyHeart :)

in infinite amount as long as we continue to go higher

I believe this might be correct, Mellie.......look at the pic.....

 Note....{DG ll CE   and GE ll DC }

Notice, that in triangle ABC, that if we pick any point "P" on DG, then triangle APD will be congruent to triangle CPD by SAS. Thus CP will be  equal to AP. But, for any point "P" that we select inside triangle CDG, then point "P" will be further from A - and certainly further from B - than "P" is from C. This is so because angle CAP will be less than angle ACP. And in any triangle, the greater angle is opposite the greater side. Thus, AP will be greater than CP.

And for the same reasons, any point "P" on GE, will make triangles BPE and CPE congruent. But, any point "P" inside triangle CEG will be further from B - and certainly further from A - than "P" is from C.

Thus....all points in rectangle CDGE will be futher from A or B than they are from C. And the area of this rectangle is just (2)(1.5)  = 3 sq units.

And the area of triangle ABC  = (1/2)(4)(3)  = 6 sq units.

So the probability that some point "P" is clser to C tham to either A or B  =  3 / 6   = 1 / 2.

2332^2 or 2332*2332=5438224

overall, your answer is:

5438224

ok It is gone - why arn't you posting under your username?

Melody, I don't take credit for answering that question. 

The website from which I posted above question, had also the answer for it.

I just pasted their correct answer here because my answer, #4 on this page, is wrong!

 I wish I could've gotten the right answer for this tough cookie. btw, I'm civonamzuk

Can someone, please erase the answer #4 on this page, it's so embarrassing.

volume:

surface area:

12*6*2+6*8.2*2+8.2*12*2=439.2 unit thingys squared

overall, your answers for volume and surface area are:

$${\frac{\left({\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\mathtt{x}}\right)}{{\mathtt{3}}}} = {\mathtt{7}} \Rightarrow {\mathtt{x}} = {\mathtt{3}}$$

X is the missing number.

One way is to take the square root after you've squared it.

Some calculators have the abs() function for returning the absolute value.
