From 11:00PM PDT on Friday, July 1 until 5:00AM PDT on Saturday, July 2, the Shmoop engineering elves will be making tweaks and improvements to the site. That means Shmoop will be unavailable for use during that time. Thanks for your patience!
Evaluate the expression 3x2 + 5xy – 2 for x = 3 and y = -2.
plug in 3 for x and -2 for y
The formula for the surface area of a cone is πrs + πr2, where r is the radius of the base and s is the length of the slant. Find the surface area of a cone with radius 10 cm and a slant of 12 cm (use 3.14 for π).
remember that surface area is written in units squared
Evaluate the expression x3 + x2 + x + 1 for x values equal to -2, -1, 0, 1, 2.
make a chart
(-2, -5), (-1, 0), (0,1), (1, 4), and (2, 15)
Which of these values of x (1, 2, 3, 4, 5, 6) make this equation true: x2 – 8x = -12?
