any ideas?

anonymous · Answer

Well  2(x+5) + 2x = 30 ?

skullpatrol · Answer

yep

skullpatrol · Answer

solve it please

anonymous · Answer

Well would you first divide 30 by 2 ?

skullpatrol · Answer

sure

anonymous · Answer

2(5+5) + 2x5 = 30
Width = 5 
since 5 would substitute for x

skullpatrol · Answer

w>5

anonymous · Answer

The part of the question that confuses me is when they say the perimeter is more than 30 mm are they looking for 30 mm as the perimeter or can it be more than that?

skullpatrol · Answer

Let P = perimeter,

 then the question asks for P > 30.

anonymous · Answer

W=10 
and the length would be 15 since the length is 5 mm longer than the width W=10 L= 15

skullpatrol · Answer

They want all values of P such that P > 30 is a true statement.

P > 30
29 > 30 False
30 > 30 False
31 > 30 True
32 > 30 True
