basic algebra and arithmetic "marathon". (3 Viewers)

You're meant to post a new question.

New Q.

Simplify:

(x – a)(x – b)(x – c) . . . (x – z)

that should be as least a 5u question

 

[ohexploitable]

that should be as least a 5u question

As above, the answer is 0 because when you get to (x - x)...

 

[Lolsmith]

No questions posted...? If so:

2x + 5y = 26
7x + 19y = 97

 

[luke42]

2x + 5y = 26
7x + 19y = 97


14x + 35y = 182 -
(14x + 38y = 194)

14x + 35y - 182 - 14x - 38y + 194 = 0

-3y + 12 = 0
-3y = -12
y = 4


14x + 35(4) = 182
14x +140 = 182
14x = 42
x = 3

14x + 38(4) = 194
14x + 152 = 194
14x = 42
x = 3


Q.

find the intergral of 10^x

 

[mirakon]

This is basic algebra and arithmetic, NOT integration.

 

[ohexploitable]

2x + 5y = 26

14x + 35y = 182 -

Q.

find the intergral of 10^x

This is for 2011ers

 

[luke42]

oh my bad.

Q.

Find the first derivative of (x+1)^2 (x+2)^2

 

[Drongoski]

(2^(2/3)+ 2^(1/3) +1)

Shouldn't the middle term be a + ?

 

[Lolsmith]

I don't think 2011'ers have done Calculus either.... not basic algebra or arithmetic.

 

[mirakon]

Shouldn't the middle term be a + ?

Yeah, my bad.

 

[ohexploitable]

Find the range of values of:

 

[hscishard]

Is it greater than or equal to 3?

I think I should post a question for incase.
Solve for x
(x+2)/(x+1)^2= 1

 

[ohexploitable]

Is it greater than or equal to 3?

I don't know either

Bob says it's:

(x+2)/(x+1)^2= 1

Something tells me it's not this simple...

New Question:



Find x and y.

New Question:



Find x and y.

how :|

 

[ohexploitable]

how :|

says a 2010er... lol

 

[bouncing]

lol what
i still dont get it

 

[ohexploitable]

lol

[hscishard]

May help if you rearrange it

Then

and


y = 6
x = 3.

Which is true if you sub it back in.

ahh okay!
that makes alot of sense thanks
