Solve for \( x \) when \( x + 4 = 10 \).

Use the quadratic formula:

\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \]

Simplify \( \frac{12}{16} \).

\[ \frac{12}{16} = \frac{3}{4} \]

Evaluate \( x^2 \) when \( x = 5 \).

The sequence term is \( a_1, a_2, a_3 \).

Simplify:

\[ \sqrt{64} = 8 \]

Expand:

\[ (x + 3)(x - 2) \]

Which value satisfies \( 2x + 1 > 9 \)?

In statistics, \( \mu \) often represents the mean and \( \sigma \) represents standard deviation.

What does this expression represent?

\[ \sum_{i=1}^{n} i \]

Evaluate the integral:

\[ \int_0^1 x^2 \, dx \]

Find the limit:

\[ \lim_{x \to 0} \frac{\sin x}{x} \]

What does \( P(A \mid B) \) mean?

Use the z-score formula:

\[ z = \frac{x - \mu}{\sigma} \]

Water is written as \( \mathrm{H_2O} \).

Carbon dioxide is \( \mathrm{CO_2} \).

Evaluate the function:

\[
f(x)=
\begin{cases}
x^2 & x > 0 \\
0 & x = 0 \\
-x & x < 0
\end{cases}
\]

Find the determinant:

\[
\begin{bmatrix}
1 & 2 \\
3 & 4
\end{bmatrix}
\]
