What is the area of the quadrilateral with vertices at (-1, 0), (2, 0), (2, 5), and (-1, 5)?

There are two sets of Y values identical ( 0 and 5 ).

There are two sets of identical X values ( -1 and 2)

This makes a rectangle.

The length is 5-0 = 5

The width is 2 - -1 = 3

Area = Length x width = 5 x 3 = 15 square units.

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
