Answer:
16 m
Step-by-step explanation:
The situation can be solved by proportion of corresponding sides in 2 right triangles.
let x be the length of shadow cast by oak tree, then
= 
( cross- multiply )
9x = 144 ( divide both sides by 9 )
x = 16
Length of shadow is 16 m
True . In the ordered pair -4 is x while -12 is y. Now that you know this you can substitute the pair into the equations.
6×-4 is -24. -24 +12 equals -12. -12=6×-4+12. Same for the second one.
