Select the two values of x that are roots of this equation.

VMariaS [17]

Answer:

x = 2, -3

Step-by-step explanation:

$x^2 + 2x- 6 = 0\\=>x^2 +3x - 2x- 6 = 0\\=>x(x+3) - 2(x +3) = 0\\=> (x-2)(x+3) = 0\\\\$

(x-2) = 0 or (x+3) = 0

x = 2 or x = -3

Thus, two values of x are x = 2, -3

Note: The options given are incorrect.

How many times greater is the value of the 3 in 4,367 than the value of the 3 in 39?

Lesechka [4]

Answer: Roughly 111.97

Step-by-step explanation:

1. 39 divided by 3 is 13.

2. 4367 divided by 3 is not evenly distributed. Rounding, it would work out to be roughly 1455.66

3. 1455.66 divided by 13 is roughly 111.97 (Again, this does not distribute evenly)

4. To check your work, multiply 111.97 times 13 and you should get somewhere around 1455.66 which is (4367 divided by 3).

Hopefully this helps! Feel free to mark brainliest! :)
