1. The problem involves expressions listed in three different boxes with algebraic terms. 2. The expressions in the center box are: - $7x - 1$ - $T7$ - $4 - x^2 -$ - $- x^2 -$ 3. We can interpret these as algebraic expressions and attempt simplification or understanding their meaning. 4. For $7x - 1$, this is a linear polynomial in $x$. 5. For $T7$, this seems to be a label or variable rather than a pure algebraic term; no direct simplification. 6. For $4 - x^2 -$, this likely represents $4 - x^2$, a quadratic function inverted in sign. 7. For $- x^2 -$, this is simply $-x^2$. 8. The expressions in the other boxes (like $14c6$, $0$, $3a$, $2x$, $V$, $U$) appear as labels or unrelated variables. 9. Since the user request ends with "Solve" but no explicit equations or target expressions are given, the best approach is to identify the function forms here: - Linear: $7x - 1$ - Quadratic: $-(x^2)$ and $4 - x^2$ 10. If the goal is to graph these or analyze them: - $y = 7x - 1$ is a straight line with slope $7$ and y-intercept $-1$. - $y = 4 - x^{2}$ is a downward opening parabola intersecting the y-axis at $4$. - $y = -x^{2}$ is a downward opening parabola crossing the origin. 11. Without further instructions or equations to solve, this completes the analysis of the expressions provided. Final answer: The key algebraic expressions are $7x - 1$, $4 - x^{2}$, and $-x^{2}$ representing a linear function and two parabolas.
