14. Which of the following is equivalent to y= x^2 – 18x + 70? y = (x – 9)^2 - 11
y = (x + 9)^2 +11
y = (x - 9)^2 +11
y = (x + 9)^2 - 11

the answer is 5636.7

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.
