Question

The rectangular pupil of an octopus is estimated to be 15 millimeters long with an area of (30x - 195)
square millimeters. Write an expression that represents the perimeter (in millimeters) of the octopus pupil.

Answer 1

Answer:

4x - 11

Step-by-step explanation:

→ Divide the area by the length to find the width

( 30x - 195 ) ÷ 15 = 2x - 13

→ Now find the perimeter by doubling each expression and adding them

2 ( 2x - 13 ) + 15

→ Simplify

4x - 26 + 15 which is 4x - 11
