Perimeter = (20 + 2x) mm.
Step-by-step explanation:
The octopus pupil has length 20 mm and the expression for its area is given by (20x - 200) square mm.
If the width of the octopus pupil is w, then 20w = 20x - 200
⇒ w = (x - 10) mm.
Therefore, the expression for its perimeter is 2(Length + Width) = 2 ( 20 + x - 10) = 2( 10 + x) = (20 + 2x) mm. (Answer)

116 , <span><span>(4 * 25) + ( 4 * 4 )
</span>4 x (25 + 4)
4 * 25
4 * 4
(4 * 25) + ( 4 * 4 ) = Distributive Property
</span><span><span>4 * 25 = 100

-12(-3) + 7
First, simplify 12 × (-3) to get -36. / Your problem should look like:
Second, add 36 + 7. / Your problem should look like: 43
Answer:
43
