Answer:

C. Add the exponents

Step-by-step explanation:

The given expression is presented as follows;

6·x·y²·z⁴·2·x²·y⁵·z

The expression can be rearranged by according to like terms as follows;

6·2·x·x²·y²·y⁵·z⁴·z = 3·2·2·x·x²·y²·y⁵·z⁴·z

By the law of indices, we add the exponents of the like terms to simplify the expression as follows;

3·2·2·x·x²·y²·y⁵·z⁴·z = 3·2⁽¹⁺¹⁾·x⁽²⁺¹⁾·y⁽⁵⁺²⁾·z⁽⁴⁺¹⁾ = 3·2²·x³·y⁷·z⁵

In order to simplify the expression the step Tim needs to use for each variable's exponent is to add the exponents.

Solve for x. The number that is cut off is 14. Suppose that both figures are similar.
Mekhanik [1.2K]

Since both rectangles are similar, the following ratio must be fulfilled:

\frac{x+9}{14}=\frac{9}{6}

By multiplying both sides by 14, we get

\begin{gathered} x+9=\frac{9\times14}{6} \\ x+9=21 \end{gathered}

and by subtracting 9 to both sides, we have

x=12

Therefore, the answer is 12.
