@Texaschic101 you are correct .75 x 64 will indeed equal 48 sq feet. so your answer will be 64 tiles. hope this was of help!
Answer:
0; 2; 6; 0 or -1
Step-by-step explanation:
If the question says "f(a)=" they are asking for the y value with the given x such as the two first ones.
If it's "f(x)=a than x=" they are asking you what x is when the (bolded) x is a given value.
If X > 0 then X must be a positive number. If Y < 0 then Y must be negative. So the quadrant that contains Positive X values and negative Y values will contain the point that you are looking for. This would be the fourth quadrant.
The answer is
<em>False

The following,

, definitely does not follow the rule given and, therefore, is not a Perfect Square Trinomial.
I hope this helped!! Have an amazing day :)
