The area of a rectangle is 42 square feet.
If the length and width are whole numbers, what are the least and greatest possible
perimeters?
26 ft. and 34 ft.
34 ft. and 86 ft.
26 ft. and 86 ft.
42 ft. and 84 ft.

26 ft and 46 ft.

Step-by-step explanation:

The prime  factors of 42 are 2 * 3 * 7.

Possible lengths and widths  are:

L = 7, W = 6 giving a perimeter of  2*7 + 2*6 = 26 ft.

L = 14 , W = 3  giving perimeter = 34 ft.

L = 21, W = 2 giving perimeter = 46 ft.

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

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
