Answer:
<h3>
R(-1, -9)</h3>
Step-by-step explanation:
When we reflect over x-axis then the x-coordinate doesn't change and the y-coordinate changes its sign
in means if R = (x, y) then R' = (x, -y)
so we have:
x = -1 and -y = 9
y = -9
which gives R = (-1, -9)
D, because if u plug it in both equation, u will get the same solution.
y=x-1
2=3-1
2=2
y=-3x+11
2=-3(3)+11
2=-9+11
2=2

Length (L): 2w
width (w): w
Perimeter (P) = 2L + 2w
78 = 2(2w) + 2(w)
78 = 4w + 2w
78 = 6w
13 = w
Length (L): 2w = 2(13) = 26
Answer: width = 13 meters, length = 26 meters
