Step-by-step explanation:
the area of a rectangle is length × width.
in our case
37 × 18 = 666 ft²
so, we need 666 ft² of tiles.
Inverse relationships are of the form xy=k or if you prefer y=k/x so to find the constant we can say:
18(0.25)=k=4.5
So you could say: IR=4.5 or I=4.5/R
Answer:
(9,21)
Step-by-step explanation:
If you plug in all the pairs, the only one that is true is (9,21).
y=x+12
21=9+12
The above equation is true, and that is why (9,21) is the answer.
Hope this helped! :)
