y=5×+630 that's question 1
the other question im not sure
-40 over 100, is the answer
Step-by-step explanation:
the question isn't complete
I think it is B. The perimeter is adding all the sides. If there isn’t a blank then the answer would be 2a + 2b, however in this problem only the AREA is taken away not perimeter.
The answer is C!!! I really hope that this helps you
