Question

1. 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.
a. Write an expression for the length in terms of the width.
b. Use expressions for the length and width to write an inequality for the perimeter,
on the basis of the given information.
c. Solve the inequality, clearly indicating the width of the rectangle.

can someone plz help me

Answer 1

a. the width is w, if the length is 5mm longer, the length is w+5

Answer 2

b. the perimeter is the sum of the sides, the figure is a rectangle, so 2 times the length plus 2 times the width, the width is w, the length is w+5
the problem says the perimeter is greater than 30
then we have:
\[\large{
2w+2(w+5)>30 \\

}\]

Answer 3

can you solve for w?

Answer 4

@2014yea ?

Answer 5

yes i'll try

Answer 6

this is what I got
2w + 2w + 10 > 30
4w + 10 > 30
4w > 20w > 5

Answer 7

yes, w >5
