Answer:
x=4
Step-by-step explanation:
-x+4=2x-8
4=2x-(-x)-8
4=2x+x-8
4=3x-8
3x=4+8
3x=12
x=12/3
x=4
We cannot determine the cost of the tiles from the given information, so the question cannot be answered.
Answer:
4(x-4.5)^2
Step-by-step explanation:
h(x)=4x^2-36x+81
=4(x^2-9x)+81
=4(x^2-9x+20.25)-(4)(20.25)+81
=4(x-4.5)^2
