Perimeter is all sides added together. A square all sides are equal. One side = .5 all sides do. So .5 x 4 = 2
(-9x²-2x) - (-9x²-3x) = (-9x²-2x) +(9x²+3x) = -9x²-2x+9x²+3x = (-9x²+9x²)+(-2x+3x) = x
Answer:
i believe its the second one.
Step-by-step explanation:
the second line plot is the one that seems most right to me
Answer:
point A' is (5, 9)
Step-by-step explanation:
A (-2,-5) is a glide reflection wear the translation is (x,y) is x+7,y and the line of reflection is y=2
A is (-2,-5)
a glide reflection wear the translation is (x,y) is (x+7,y)
7 is added with x, so add 7 with x value -2 on A(-2,-5)
(-2+7, -5)
(5,-5)
Reflection is y=2
So we need to find the difference of y values of point (5,-5) and y = 2
2-(-5) = 7
So we move 7 units up from y = 2. y=2+7 = 9
x value remains the same x=5
Hence point A' is (5, 9)
24, just do 6x4 because there are 4 sides.
