Answer:

90 minutes

Step-by-step explanation:

From the question, we are told that every second , 50 bars are eating

Since there are 60 seconds in a minute;

This means that ;

in 1 minute; 60 * 50 = 3,000 bars would have been eaten

Now, let us calculate what will be eaten in 1 hour

There are 60 minutes in an hour

The number of bars eaten in an hour will be;

60 * 3,000 = 180,000 bars

So, 180,000 bars are to be eaten in an hour

From the question, the production rate of the company is 2,000 bars per minute

so, the time it will take to produce what will be enough to be eaten in an hour will be;

180,000/2,000 = 90 minutes

<span>(-14 + 3/2b) - (1 + 8/2b)
= -14 - 1 + 3/2b - 8/2b
= -15 - 5/2b

In short, Your Answer would be Option C

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)
