<h2>Hey there!</h2>

<h2>Given,</h2>

       length = 2x-5 and breadth(width) = x+9

<h3>We know that:</h3><h3>Perimeter of a Rectangle is = 2*(l + b)</h3>

                                             = 2*(2x-5 + x +9)

                                             = 2*(x+4)

                                             = 2x + 8

<h3>So, the perimeter of the given rectangle is = 2x + 4</h3><h3 /><h2>Hope it help you</h2>

Monica [59]

Answer:

55.27 miles

Step-by-step explanation:

Hello, I think I can help you with this

you can easily solve this by using a simple rule of three

Step one

If 1 mile is approximately 1.61 kilometers,it is

1 miles ⇔ 1.61 Kilometers

the, how many miles(x) are 89 km?

x ⇔  89 kilometers

the relation is

\frac{1\ mile}{1.61\ km}=\frac{x}{89\ km} \\

Step two

solve for x( isolating x)

\frac{1\ mile}{1.61\ km}=\frac{x}{89\ km} \\\frac{1\ mile*89\ km}{1.61\ km}=x\\x=55.27\ miles

55.27 miles

german
You have 49 hamburgers in total, 24 on the grill and the rest are in the fridge and represented by the variable H.

we know that the 24 hamburgers on the grill, when added to the number of hamburgers we have in the fridge, have to equal the total number of hamburgers, 49.

so 24+h=49, or 49=24+h depending on how you're supposed to write your answer
