sorry this is good A student accidentally added five to both the numerator and denominator of a fraction, changing the fraction's value to 1/2 . If the original numerator was a 2, what was the original denominator?\

did u get the answer

Your question is incomplete

In f(x) the coefficient of x^3. is  4

In g(x) it is -6

-6×(4/6)=-4

So the coefficient is   2/3

((G(x)+f(x))((g(x)-f(x))

=( g(x))^2  -   (f(x))^2

= (x^2+1)^2.  -   (x+5)^2

= (x^4+2x^2+1)  -  (x^2+10x+25)

=    x^4  +x^2.  -10x.    -24

S   atan(75/26)  W

X^2+y^2=2.5^2

Thanks Alan 

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)

My bad I just noticed I didn't need Gauss on this one.

But the constant = 0.

How can you solve this if you can't even find the potential rationnal roots, as 0 cannot be divided?

Your formula is written wrong!!. First, your interest rate is way too small. It is actually 1/10 of 1%. I believe it should be at least 1%. Second, you are subtracting 1 twice. It should be subtracted only once. I believe your formula should look like this:

100*{(1 + .01/12)^12 - 1} / (.01/12)

100 * 12.05515=1,205.52

The probability is ≈0.0727859 x 100 ~7.28%

1. 8 + (9t + 4)  --> combine like terms

12+9t

2. 9(2x)  --> multiply 

18x

3. (4 + 105x) + 5  --> combine like terms

105x+9

4. 10p(11)  --> multiply

110p

5. (12r)13  --> multiply 

156r

6. (2+3x)+9  --> combine like terms

11+3x

7. 4(x6.3) --> multiply

25.2x

8. 1.1 + (7d + 0.1)  --> combine like terms

7d+1.2

9. 56ab/b  --> combine like terms

56a

10. 1.5mn/m  --> combine like terms

1.5n

11. 13p/pq --> combine like terms

13/q

12. 33xy/3x  --> combine like terms

11y

When multiplying two negatives together, you multiply the numbers like you usually do, but the negative signs cancel each other out, so the product ends up being possitive. 

In this case, -2*-2 = 4. 

See how WolframAlpha interprets this :

Do you have it written correctly???

What is the common ratio for the range of -1,-0.75,-0.5?

There is no common ratio.
The quotients are unequal.

ln e  = 1

But...if we have something like this

ln (3e).....this equals     ln 3   + ln e    =   ln (3 ) + 1

Or...if we have something like this

ln e^3  .......this equals   3ln e   =  3 * 1  = 3

What is the common difference for the range of -1,-0.75,-0.5?

-0.25

HOW DO YOU SOLVE THIS?

\((-1)-(-0.75)=-0.25\)

\((-0.75)-(-0.5)=-0.25\)

I believe this is correct:

 240kPa / 290K  = ? / 320K     multiply both sides by 320K

[320K / 290K] * 240kPa  ≈  264.83kPa

32/41+78*12-3.25

\(\frac{32}{41}+48\times 12-3.25 \) = \(573.530487805\)

1. 8 + (9t + 4)    =  8 + 4 + 9t =   12 + 9t

2. 9(2x)    =  18x

3. (4 + 105x) + 5     =     4 + 5 + 105x  =  9 + 105x

4. (10p)11    =     110p

5. (12 * r) * 13    =   13 * 12 * r =  156r

6. (2 + 3x) + 9   = 2 + 9 + 3x  =  11 + 3x

7. 4 * (x * 6.3)  =  4 * 6.3 * x =   25.2x

8. 1.1 + (7d + 0.1)   =   1.1 + 0.1 + 7d =   1.2 + 7d

9. 56ab/b  =  56a

10. 1.5mn/m    =  1.5n

11. 13p/pq    =  13/q

12. 33xy/3x  =  11y

7 = 5/x      multiply both sides by x

7x = 5      divide both sides by 7

x = 5 / 7

The common difference is -0.25

 your not helpful but also some of the questions are wrong!!!
