Rearrange Line 1 and Line 3’s equations in the form of y = mx + c for easier comparison.
Lines 1 and 2 are parallel, because they have the same gradient.
Lines 1 and 3, and 2 and 3 are neither, because their gradients do not multiply to form -1.
(Gradients of perpendicular lines multiply to form -1.) c
Let the length of the rectangle is x. units , accordingly :
2.(x+3) = x×3.
2x + 6 = 3x.
x = 6 units is the answer :)
Answer:
C :She is incorrect because she should have squared each leg length and then found the sum
Hmm, the 2 numbers are most likely whole numbers
find what adds to 10 and find teh LCM

3 and 7, LCM is 21, nope
4 and 6, LCM is 12, yep
the nmbers are 4 and 6
I believe it's 37CM, I had that question on my finals last year.
