A rectangle has a a width of 9 inches the area is 648 inches what is the length of the rectangle

Answers

Answer 1
Answer: The formula for a rectangle is length*width=area. Since we know the area and the width, we plug it in to the formula, we get length*9=648. 
l*9=648 is equivalent to l=648/9. Now we solve l=648/9 and get l=72. SO the width is 72 inches.

X has coordinates (a,3a) and Y has coordinates (-5a,0). Find the coordinates of the midpoint of XY

Answers

For this case we have that by definition, the midpoint of a segment is given by:

XY = (\frac {x1 + x2} {2}, \frac {y1 + y2} {2})

We have the following ordered pairs:

(x1, y1) = (a, 3a)\n(x2, y2) = (- 5a, 0)

Therefore, substituting values we have:

XY = (\frac {a-5a} {2}, \frac {3a + 0} {2})

Rewriting we have:

XY = (\frac {-4a} {2}, \frac {3a} {2})\n

XY = (- 2a, \frac {3a} {2})

Answer:

the coordinates of the midpoint of XY

XY = (- 2a, \frac {3a} {2})

Estimate it: 180.8 divided by six
