2(x+3)=15-x
2x+6=15-x
+x +x
3x+6=15
-6 -6
3x=9
/3 /3
x=3
Answer:
2578
Step-by-step explanation:
A Glide Reflection is the composition of a translation and a reflection across a line parallel to the direction of translation.
A = L * W
A = 135
L = 2W - 3
135 = W(2W - 3)
135 = 2W^2 - 3W
-2W^2 + 3W + 135 = 0
(-2W - 15)(W - 9) = 0
-2W - 15 = 0
-2W = 15
W = -15/2....not this one because it is negative
W - 9 = 0
W = 9 <=== the width is 9 ft
L = 2W - 3
L = 2(9) - 3
L = 18 - 3
L = 15 <=== length is 15 ft
