Mario is constructing a frame for a 10inches by 8inches photo. he wants the frame to be the same width all the way around and the total area of the frame and the photo to be 120 square inches. what are the dimensions of the frame?

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.

If 3x+8=3x+8 is it one solution or no solution

If f(x) = 3x2 - 2x+4 and g(x) = 5x + 6x - 8, find (f-g)(x).
