Solve each problem. Grant Wood painted his most famous work, American Gothic, in 1930 on composition board with perimeter 108.44 in. If the rectangular painting is 5.54 in. taller than it is wide, find the dimensions of the painting. (Data from The Gazette.)

Solve each problem. The Bermuda Triangle supposedly causes trouble for aircraft pilots. It has a perimeter of \(3075 \mathrm{mi}\). The shortest side measures 75 mi less than the middle side, and the longest side measures 375 mi more than the middle side. Find the lengths of the three sides.

Solve each inequality. Graph the solution set, and write it using interval notation. $$ |4 x+1| \geq 21 $$

Solve each compound inequality. Graph the solution set, and write it using interval notation. $$ x \geq 1 \quad \text { or } \quad x \geq 8 $$

Solve each equation, and check the solution. If applicable, tell whether the equation is an identity or a contradiction. \(4(x-2)+2(x+3)=6\)

In \(2007,\) rain shortened the Indianapolis 500 race to \(415 \mathrm{mi}\). It was won by Dario Franchitti, who averaged \(151.774 \mathrm{mph}\). What was his time to the nearest thousandth?

Solve each inequality. Graph the solution set, and write it using interval notation. $$ |-5 x+3| \geq 12 $$

Solve each compound inequality. Graph the solution set, and write it using interval notation. $$ x \geq-2 \quad \text { or } \quad x \leq 4 $$

Solve each equation, and check the solution. If applicable, tell whether the equation is an identity or a contradiction. \(-2(x+3)-x-4=-3(x+4)+2\)
