(x-4)^2-19=y
you first add the three to the other side, then add 16 on both sides, make the left side x-4 squared, and lastly you subtract 19 from both sides.
Answer:
Step-by-step explanation:
The answer is C
The area for the perimeter of a rectangle is:
<em>P = 2l + 2w</em>
In this problem, we are given that
P = 155 and
l = 45.5. To solve for area, we must find w. To do this, plug in the given info and isolate the w like so:

Now we know
w = 32. Knowing all the necessary info, we can use the area formula, <em>A=lw</em>, to solve for A.

The area is
1,456 sq ft. Hope this helps!
Distance = speed x time
Distance = 240 x 3 = 720 miles
So than there are
1x -5y =15
-1x +5y = -15
--------------------assuming term by term we get
0 0 = 0
so from what result that this system has infinitely many solutions
hope helped
