Answer:
For x = height:
x(x + 20) = 576.
Step-by-step explanation:
The area is 576 cm^
Area = width * height
Let the height be x, then the width is (x + 20) cm
So the expression for the area can be written
x(x + 20) = 576.
<span>A line segment LM is drawn. Two arcs equidistant from L on line LM are drawn at points P and T. A point Q is just above L. A compass is fixed at point Q and is shown making an arc at T.
</span>You draw arcs centered at P and T, such that they intersect above and below L. Note that the arcs must have radius greater than LT=LP.
<span>I get the feeling that Q is where the arcs intersect above L, so the intersection below L (at, say, S) means that QS is perpendicular to LM. </span>
<span>Incidentally, constructing LM does not really fit the bill to start with, since either P or T must be beyond the line segment. What it should say is that points L and M are marked on a line extending beyond LM.</span>
