What is the value of c? 7x2
7x4 + 4x – 20
–
can be factored into the form
(ax + b) (x + c)

The correct answer is: b

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

The answer here would be 10
