Find the factors and zeros of 6x^2 +8x-28=2x^2 + 4
Mice21 [21]

Answer:

First solve the equation:

6x^2 + 8x -28 = 2x^2 + 4

=> 6x^2 - 2x^2 + 8x - 28 -4 = 0 => 4x^2 + 8x - 32 = 0

Extract common factor 4:

=> 4[x^2 + 2x - 8] = 0

Now factor the polynomial:

4(x + 4) (x - 2) = 0

=> the solutions are x + 4 = 0 => x = -4, and x - 2 = 0 => x = 2.

So the answer is the option B: 4(x + 4)(x - 2); {-4, 2}

HOPE THIS HELPS! :D

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
Butoxors [25]

The mean of a dataset is simply the sum of the elements, divided by how many elements you have.

In your case, you have a dataset of 10 elements, so we will divide by 10.

The sum of the elements is

5+8+9+11+7+7+8+9+12+7=83

Which implies that the average is

\dfrac{83}{10}=8.3

Which should be approximated to 8.
