Lines A and B are parallel to each other. Lines B and E are perpendicular to each other.
Answer:
6 and 21 meters long
Step-by-step explanation:
You make an equation from what you got (there are 2 widths and 2 lengths)
2(4w-3)+2w=54---->10w-6=54---> 10w=60 ----> w=6 ---> plug in the rest and you get 21 as the length.
or... make W+L=28 and guess and check!!! takes longer but works!
X^2 + 3x - 4 = 6
x^2 + 3x -10 = 0
(x + 5)(x - 2) =0
x = -5 or x = 2
solution set is {-5,2}
(-1,8) and (5,6) are points on the line.
Slope of line = (8-6)/(-1-5) = 2/(-6) = -⅓
y-6 = -⅓(x-5)
y = -⅓x + 5/3 + 6 = -⅓x + 7⅔
