Answer:
(-1, -3)
Step-by-step explanation:
The midpoint coordinates are the average of the respective end point coordinates:
M = (P +Q)/2
M = ((-7, 1) +(5, -7))/2 = (-7+5, 1-7)/2 = (-2, -6)/2
M = (-1, -3) . . . . the midpoint of PQ
Suppose width is X
then length would be X+44
perimeter of rectangle = 2 (length + width)
substitute:
328 = 2 ( X+44 + X )
328 = 2 ( 2X + 44 )
328 = 4X + 88
328 - 88 = 4X
240 = 4X
240/4 = X
X = 60
substitute in the first and second line
width is X so width = 60 feet
length is X + 44 = 60 + 44 = 104 feet
Answer:
9
Step-by-step explanation:
If A = - 3, than A^2 is equal to (-3)^2
If a number is squared (to power of 2), it is multiplied by itself (there are two of that number being multiplied together) so it is - 3x-3
-3 x - 3 = 9,
Because 3x3 =9 and a negative multiplied by a negative makes a positive.
