<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

Juanita begins to factor an expression as shown. x2+3x−18=(x+)(x−) What numbers should be placed in the boxes from left to right
stich3 [128]

Answer:

Option A is the correct answer.

Step-by-step explanation:

Here we need to factorize  x²+3x−18

The coefficient of x is 3 and the constant is -18

Which means

           The sum of factors is 3

           The product of factors is -18

The factors satisfying are  6 and -3

Here the factors are given in the type (x+)(x−)

     So the value after plus is 6 and value after - is 3

Option A is the correct answer.

<span>rate = distance/time
</span>r = 
so it would be
r =  miles per minute

Or if it was miles per hour:

Cross multiplication gives us
45x = 240
