Alimited-edition poster increases in value each year. after 1 year, the poster is worth $20.70. after 2 years, it is worth $23.81. which equation can be used to find the value, y, after x years? (round money values to the nearest penny.)
y = 18(1.15)xy = 18(0.15)xy = 20.7(1.15)xy = 20.7(0.15)x

answer: are you

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
