Factor quadratic equation 6x.squared +41x + 63 = 0
vlabodo [156]

Answer:

x1= -9/2 ; x2= -7/3

Step-by-step explanation:

Rewrite to 6x^2 + 27x +14x +63 = 0

Factor and get 3x(2x + 9) + 7(2x + 9) = 0

Factor again and get (2x + 9)(3x + 7) = 0

Separate into possible cases -> 2x + 9 = 0; 3x + 7 = 0

The equation has two solutions: x1 = -9/2 and x2 = -7/3

Hope this helped!!

When a number is decreased by 4%, the result is 93. What is the original number
romanna [79]

Answer:

<u>The original number is 96.875</u>

Step-by-step explanation:

Let's find the original number using the Direct Rule of Three, this way:

       Percentage          Number

              100                       x

               96                       93

***********************************************

96x = 93 * 100

96x = 9,300

x = 9,300/96

x = 96.875

<u>The original number is 96.875</u>

2. To rewrite  you have to multiply the numerator and denominator by three since the lcd is 12. So you're new fraction will be . For the second fraction, since the lcd is 12 you will multiply the numerator and denominator by 4. You're new fraction will be .

3. Since the problem contains the math keyword "Further", you automatically know you have to subtract, now subtract  - . First, start of by subtracting the numerators, so subtract 9-8=1 , remember the denominators will always stay the same.

In conclusion, you're answer will be , so Isabel lives  farther away from Janet.
