<h2>Answer:        <u>  (-5x⁴)(√(4x + 7))  </u></h2><h2>                                4x + 7</h2>

<h3>Step-by-step explanation:</h3>

The question is asking us to make the denominator a rational function by finding a way to remove the square root without changing the value of the overall function.

We can do this by multiplying the denominator and numerator by the √(4x + 7), since multiplying a root term by that root term = the number being rooted  (√x × √x = x).

<u>    - 5x⁴      </u>   ×     <u>  √(4x + 7)   </u>  =  <u>  (-5x⁴)(√(4x + 7))  </u>

√(4x + 7)              √(4x + 7)                 4x + 7

Coffee with sugar and milk added to it can contain up to calories. To consume a maximum of 600 mg if caffeine per day, how many
Marina CMI [18]
We know there is 330 mg of caffeine per 16-ounce serving. So if we want 8-ounce servings:
330 mg : 2 = 165 mg
Also we have to consume a maximum of 600 mg.
165 mg * 3 = 495 mg < 600 mg
165 mg * 4 = 660 mg > 600 mg
Answer: Someone could drink 3 full 8-ounce servings in a day and still stay below the limit.

12. The sum of three consecutive integers is 12 more than twice the largest integer. Which of the following
baherus [9]

Answer:

OPTION 4

Step-by-step explanation:

Let the three consecutive numbers be n, (n + 1) and (n + 2).

Note that the largest number of the three is (n + 2) and the smallest is n.

So, according to the given data, the sum of all the three integers is equal to 1 more than twice more than the largest number.

Writing it mathematically, we have:

n + (n + 1) + (n + 2) = 12 + 2(n + 2)

This is OPTION (4) and is the answer,
