Answer:
35 miles per hour
Step-by-step explanation:
175 -140 = 35
35/1 = 35
M= 276 31+276=307.
307-31=276 that’s how I found M
I think that the answer is A.
Just like you drew those dotted lines. You know how to find the areas of rectangles which is A=length x width
The answer would be 20cm^2+6cm^2+18cm^2=44 cm^2
