Hmm, how did you work it out? I can't remember what I exactly put.

I got 15cm squared for the badge question. Area of rectangle = 18 cm squared - area of triangle = 3 cm squared

its really annoying because i worked it out wrong but i knew how to do it, i just wrote down the wrong sign.

2y+x=5 through the point (3,7)

2y+x=5 (divide by 2)
y+x/2 = 2.5 (-x/2)
y=-x/2 +2.5

m X m perpendicular = -1
-0.5 X m perpendicular = -1 (divide by -0.5)
m perpendicular = 2

y=2x+c
7=2X3+c
7=6+c (-6)
1=c

answer: y=2x+1

I think I done really bad on this paper. Was the rationalize denominator answer 2 root 6?
