The rectangular garden has an area represented by 15x2 - 4x - 4 square meters and a length represented by 5x + 2 meters. Find a binomial that represents the width. a. 2x - 3 m
b. 2x + 3 m
c. 3x - 2 m
d. 3x + 2 m

Answer it Correctly or I will REPORT your answer!

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
