Solve the equation using the quadratic formula.
-x^2+27 = 6x
x=-3, X=9
X=-3X=3
x=-9,f=3
x=-9, x=3

The value of x is -9 and 3.Option D.

Step-by-step explanation:

Given,

To find the value of x.

We will apply middle term factor formula.

The given equation can be written as,

or, +(9-3)x-27 = 0

or, x²+9x-3x-27= 0

or, x(x+9)-3(x+9)=0

or, (x+9)(x-3) = 0

So, x = -9 and x = 3

Hence,

The correct option is Option D.

The answer to your question is 16/49

Step-by-step explanation:

Data

4/7 ÷ 1 3/4

Process

1.- Convert the mixed fractions into improper fractions

1 3/4 = (4 + 3) / 4 = 7/4

2.- Divide

       4/7 ÷ 7/4 = 16/49

3.- Simplify

I think it is not possible to simplify.

4.- Also we can solve this problem by converting the division into a multiplication, just invert the second fraction.

      4/7 x 4/7 = 16/49

The result is the same.
