Given data:
The first given length is AC=53.
The second given length is AB= 45.
The expression for the Pythagoras theorem is,

Here, consider only positive sign of BC length as side cannot negative.
Thus, the BC length is 28.
Answer:
(x -6)²
Step-by-step explanation:
It is worth remembering the form of the square of a binomial:
(a +b)² = a² +2ab +b²
Note that if "a" and "b" have different signs, the middle term will be negative.
In your case, the square root of the constant is half the magnitude of the x-coefficient, so the trinomial you have is a perfect square. Since you just found √36 = 6, and the sign of 12 tells you the terms have different signs, you know the answer is ...
x² -12x +36 = (x -6)²
_____
Of course, you recognize (x +6)(x -6) as the factoring of the difference of squares ...
x² -6² = x² -36
which is not what you have.

3.) y-intercept = 2. The graph will be a straight line passing through points (0, 2) and (2/3, 0)
4.) y-intercept = -1. The graph will be a straight line passing through points (0, -1) and (2, 0)
5.) y-intercept = 2. The graph will be a straight line passing through points (0, 2) and (3, 0)
To find the average speed she goes in one mile, simply divide 21 by 4, this gives you 5.25.
To get the answer for part B, divide 42 by 5.25, Wich gives you 8. You can always check your work by doing the opposite as you did to solve, so 8 x 5.25 should equal 42, which it does.
