x=-3 is a zero of multiplicty one and x=3 is a zero multiplicty of two while the lead co efficient is one

don't understand sorry

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

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.
