Expand and simplify: 3(x-y)+4(x+2y)

The table above shows approximate conversions from gallons to liters. what is the value of x?

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.

Use the distributive law to multiply. 3(4x + 5y + 6)
