                          = 1/2 × 7 × 11
                          = 38 1/2 × 4 = 154
                             7 × 7 = 49
                          = 154 + 49
                          = 204in³

Rectangular Prism- SA= 2lw + 2lh + 2wh
                             = 2 × 11 × 7 + 2 × 11 × 7 + 2 × 7 × 7
                             = 154 + 154 + 98
                             = 406in³

Therefore, the rectangular prism has the larger surface area.

Answer:

\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:x=-2,\:y=2}

Step-by-step explanation:

\begin{bmatrix}-7x-6y=2\\ 7x+4y=-6\end{bmatrix}

\mathrm{Substitute\:}x=-\frac{2+6y}{7}

\begin{bmatrix}7\left(-\frac{2+6y}{7}\right)+4y=-6\end{bmatrix}

\begin{bmatrix}-2-2y=-6\end{bmatrix}

\mathrm{For\:}x=-\frac{2+6y}{7}

\mathrm{Substitute\:}y=2

x=-\frac{2+6\cdot \:2}{7}\\\\x=-2
