If two similar triangles have side lengths 3cm and 7cm then we can determine that the scale factor for the lengths is: 7/3
Now, we have to work out the area scale factor !
This is simple, since area is given in cm² then all we have to do is square our original scale factor!
So,
7/3² = 49/9
So, we can say that the ratio of the area would be:
x : 49/9x

Parallel. This is pretty simple if you either a) Picture it in your head, or b) look at each option logically. lets try out b)
The last option does not really apply to lines, and is for angles. (unless your talking about the adjecent sides of an angle, but this would mean they meet at a vertex) Perpendicular, doesnt make sense because if they were perpindicular on a plane, (2-d) then it would be immpossible for BOTH to be parallel to a third line. This leaves the first option, which makes sense.
Answer:
Step-by-step explanation:
Given
Required
Find x and y
To eliminate x, we simply add both equations
Divide by 9
Substitute -3 for y in
Add 15 to both sides
Divide by 9
