Three vertices of a square have coordinates (5, 1), (2, -2), and (-1, 1). What are the coordinates of the fourth vertex?
Answers
plot the points we notice that the square is tilted diagnaol
remember that the legnths of the diagonals of a square are equal
therefor the distance between the points (5,1) and (-1,1) is the same as the ohter diagonal (distance is 6)
the other point is probably that disance up or the y vairable (2,-2)+6 on the y -2+6=4 (2,4) answer is (2,4)
What is the perimeter of a trapezoid having side lengths of 20 ft, 20 ft, 26 ft and 18 ft?
Answers
Hello! :) So we know perimeter means around, right? So we would do 20 + 20 + 26 + 18 which equals 84. Finally 84 ft is our answer!
Hope it helps! :)
I think it's about 84 ft

I need the answer and the work! you have to find n.
Answers
Tell you what I'll do: I'll show you the work, for two of them. Then, knowing how to do it, you'll find the answers. Deal ?
#1). n + (-13) = -12
Remove the parentheses on the left side: n - 13 = -12
Add 13 to each side: n = 1
================================
#3). -15 + n = 3
Add 15 to each side: n = 18
OK. Look those over, understand how they're done, then TAKE IT !
