Answer: 16

its just x plus 1/3 of x. This is harder to find so youre probably not expected to find it this way.

Actual way to solve it.

set up proportion.

\frac{3}{4} = \frac{12}{x}

cross multiply

3 x x = 3x

12 x 4 = 48

48 = 3x

divide by 3 to get x

48 / 3 = 16

x = 16

Factor completely 3x^2+2x-1
Morgarella [4.7K]

Answer:

(3x - 1)(x + 1)

Step-by-step explanation:

3x^2 factors into 3x and x.

-1 factors into -1 and 1.

Now we try different positions of 3x, x, -1, and 1 until we find the correct factorization.

Try: (3x - 1)(x + 1)

When you multiply the two factors together, the middle term will be 3x - x = 2x

Since 2x is the original middle term, this is the correct factorization.

Answer: (3x - 1)(x + 1)
