Answer:

x^2 + 10x - 13y.

Step-by-step explanation:

3(2x + y) + 4(x - 4y) + x^2 First apply the Distributive law to the parentheses:

= 6x + 3y + 4x - 16y + x^2 Now add like terms:

= 10x - 13y + x^2.

Again, In this question too you need to substitute the given variable values into the original expressions. Here, "x" is given as a value of "12" and the variable of "y" is given as as value of "2". A single variable of "x" in the numerator is given in the expression. On the denominator the variable of "y" with a value of "2" is multiplied by a numbered value of "3". So, now showing this by the help of LaTeX.

$\mathbf{Since, \: x = 12, \: y = 2}$

$\mathbf{\therefore \quad \dfrac{12}{3 \times 2}}$

$\mathbf{\therefore \quad \dfrac{12}{6}}$

$\mathbf{2}$

$\boxed{\mathbf{\underline{\therefore \quad Final \: \: Answer \: \: is: \: B) \: 2}}}$

Hope it helps.
