Answer:
length = 17cm, width = 10cm
Step-by-step explanation:
2L + 2w = 54
L = w + 7
Substitute:
2(w + 7) + 2w = 54
2w + 14 + 2w = 54
4w = 40
w = 10
L = 10 + 7 = 17
9 - 2(7 - 8)
9 - 2(-1)
9 - (-2)

X=0.84....................
Here
we can see that the problem gives us the length of a sandwich of x =
1.2. The problem also asks us for the expression that better
represents the approximate length of the crust given among the
options above. Here we simply have to substitute x to each of the
choices.
The
answer is B) x = 8x² + 34; 45.52 centemiters

hope it helps, Regards.
Statement : Val spent $ 34 for the 2 items
contradiction : Neither of the 2 items that Val bought cost more then $ 15
think about it....if neither of them cost more then 15....lets say they cost 15 each...then there is no way he spent $ 34.....he would spend at most $ 30
