Students hiked 32 miles on a 4 day hiking trip. at that rate, how many miles will the students hike on a 6 day hiking trip.

Solve 2^x=32 and rewrite this equation in a logarithmic form

The fence around a quadrilateral-shaped pasture is 3a^2+15a+9 long. three sides of the fence have the following lengths: 5a, 10a-2, a^2-7. what is the length of the fourth side of the fence?

Parabolas y=−2x^2 and y=2x^2 +k intersect at points a and b that are in the third and the fourth quadrants respectively. find k if length of the segment ab is 5.
