Answer:
568 m (squared)
Step-by-step explanation:
20*18=360

Answer:
if you mean y=3x, then yes
Step-by-step explanation:
solution:
substitute s by -3, we obtain
y= 3 (-3)
y= -9
So, if x= - 3 then it's y= - 9
Answer:
multiply the scale drawings side lengths by the scale
Step-by-step explanation:
for instance, if i have a square shaped scale drawing with the side lengths of 4in, and the scale is 2in, i would multiply 4 by 2, and the actual drawing's side lengths would be 6.
if i did not know the scale and i knew the actual drawings side lengths and the scale drawings side lengths, i would divide the corresponding lengths
example: rectangular scale drawing with the lengths, 5, 5, 10, and 10. and an actual drawing with the lengths 10, 10, 20, and 20. if i divide 20 by 10 or 10 by 5, i'd get 2, the scale
