Jaylin created the following expression: 100 POINT CORRECT ANSWER ONLY
25x −310 − x + 1710x − 110
Jaylin created an equivalent expression using the following steps:

410x + (−1x) + 1710x + (−310) + (−110)1110x + −25
Is his final expression equivalent to the initial expression? Show how you know. If the two expressions are not equivalent, find Jaylin's mistake and correct it.

Find the required measurements of the following trapezoids. a = 8 cm b = 16 cm h = 10 cm

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.
