IceJOKER [234]
There are several approaches.

(5/3)x^2 - 5 = 0 has the coefficients a=5/3, b=0 and c = -5.

Thus, the quadratic formula would be appropriate here:

         -0 plus or minus sqrt(0^2 - 4(5/3)(-5) )
x  = -------------------------------------------------------
                                 2(5/3)
         plus or minus sqrt(100/3)
    = ------------------------------------
                         10/3
            3      10
     = ------* ----------- = sqrt(3)    (answer)
          10     sqrt(3)

An arithmetic sequence "a" starts with 84, 77 define "a" recursively
sweet [91]

Answer:

First, let's define an arithmetic sequence:

In an arithmetic sequence, the difference between any two consecutive terms is always the same.

Then we can write it in a general way as:

aₙ = a₁ + (n - 1)*d

where:

aₙ is the n-th term of the sequence.

d is the constant difference between two consecutive terms.

a₁ is the initial term of our sequence.

Now in this case we know that the first terms of our sequence are:

84, 77, ...

Then we know the initial term of our sequence:

a₁ = 84.

And the value of d can be calculated as:

d = a₂ - a₁ = 77 - 84 = -7

Then the general way of writing this sequence is:

aₙ = 84 + (n - 1)*(-7)

And the recursion relation is:

aₙ = aₙ₋₁ - 7

So for the n-th term, we must subtract 7 of the previous term.

6d^2+33d+27, what is the answer?
m_a_m_a [10]
6d^2+33d+27 \\ \\ GCF = 3 \\ \\ 3( \frac{6d^2}{3} +  \frac{33d}{3} +  \frac{27}{3} ) \\ \\ 3(2d^2 + 11d + 9) \\ \\ 3(2d^2 + 9d + 2d + 9) \\ \\ 3(d(2d + 9) + (2d + 9)) \\ \\ 3(2d + 9)(d + 1) \\ \\

The final result is: 3(2d + 9)(d + 1)
