Help pls with math lotsss of points!!!

Answer:

5x^2+22x-12         x cannot be -5, -4, -2

(x+5)(x+4)(x+2)

Step-by-step explanation:

In order to solve this, your denominator must be the same. Let's start by writing out the two different quadratic formulas:

x^2 + 6x + 8 <-- This should factor out to (x+4)(x+2)

x^2 + 7x + 10 <-- This should factor out to (x+5)(x+2)

Now that you have factored out the two quadratics, plug them into the equation.

    5x        -       3

(x+4)(x+2)      (x+5)(x+2)

Now as we know, -2 cannot be x because it will turn the entire equation undefined. Multiple top and bottom with (x+5) on the right side and (x+4) on the left side.

5x (x+5)             -           3(x+4)  

(x+5)(x+4)(x+2)      (x+5)(x+4)(x+2)

Focus on the top. 5x(x+5) will turn out to be 5x^2+25x. 3(x+4) will turn out to be 3x+12. Combine the two equations because now they are equal to each other and do the subtraction:

5x^2+25x - (3x+12)     =    5x^2+22x-12         x cannot be -5, -4, -2

 (x+5)(x+4)(x+2)               (x+5)(x+4)(x+2)

suter [353]

Answer:

t = k \frac{1}{s}  \\ 2 = k. \frac{1}{60} \\ k = 120 \\ k \:  \: is \: constant \: of \: variation \\ relationship \: is  \\ t =  \frac{120}{s} . \\ when \: s \:  = 90 \\ t =  \frac{120}{90}  \\ t =  \frac{4}{3}  \\ when \: t = 2 \frac{1}{2}  \\ s =  \frac{120}{2 \frac{1}{2} }  \\ s = 48
