Question

The length of a rectangle is 5 mm longer than its width. Its perimeter is more than 30 mm. Let w equal the width of the rectangle.

Answer 1

any ideas?

Answer 2

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

Answer 3

yep

Answer 4

solve it please

Answer 5

Well would you first divide 30 by 2 ?

Answer 6

sure

Answer 7

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

Answer 8

w>5

Answer 9

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?

Answer 10

Let P = perimeter,

then the question asks for P > 30.

Answer 11

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

Answer 12

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
