If 3a + 3 (b + 1) = C, what is b + 1 in terms of a and c?

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's

20000 as first it increases by 2500 then by 5000 so next it will increase by 10000

It’s c. i’m almost sure
