The length of a given rectangle is six more than twice its width. Write a fully simplified expression to represent its perimeter.

Step-by-step explanation:

Represent the length with x and width with y

By analysis, we have:

Length = 6 + 2 times the width.

Mathematically, the expression is:

Required: Determine the perimeter

Perimeter of a rectangle is calculated as:

Substitute x for length and y for width

Substitute 6 + 2y for x

Open bracket

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
