The area of a rectangular school yard is given by the equation x^2 + 13x + 42 as measured in square yards. The teacher wants you to run the length. How far will you run if x = 33?

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.

Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie
