Arectangular price tag has an area of 36 square centimeters. its perimeter is 26 centimeters. what are the dimensions of the price tag?

4 cm by 9 cm

Step-by-step explanation:

The formula for area of a rectangle is A = LW, where L and W are the dimensions of the rectangle.  We have

36 = LW

The formula for perimeter of a rectangle is P = 2L + 2W.  We have

26 = 2L + 2W

Solve the area formula for any variable..

36/L = W

Plug that into the perimeter equation..

26 = 2L + 2(36/L)

Now simplify...

26 = 2L + 72/L

Multiply all 3 terms by L to get rid of the fraction...

26L = 2L² + 72

Now this is a quadratic equation, get all terms to one side and solve...

2L² - 26L + 72 = 0

Divide both sides by 2

L² - 13L + 36 = 0

Factor the left side

(L - 9)(L - 4) = 0

So L = 4, or 9

If L = 4, then W = 36/4 = 9

If L = 9. then W = 36/9 = 4

either way, the dimensions are 4 cm by 9 cm

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
