If the answer is 5 why isn't 5 an option?

Suzanne wants to put a fence around her square garden. If the garden covers an area of 49ft^2, how many feet of fencing does she

lina2011 [118]

Answer:

The area for a square is given by:

$A = x^2$

And we can find the dimension for one side like this:

$x = \sqrt{A}$

Replacing we got:

$x = \sqrt{49 ft^2}= 7ft$

Then since we are interested in the how many feet of fencing does she need, we can find the perimeter given by:

$P = 4x$ and replacing we got:

$P = 4*7 ft = 28 ft$

Step-by-step explanation:

For this case we know that Suzanne want to put a fance around a square garden with an area of 49 ft^2

The area for a square is given by:

$A = x^2$

And we can find the dimension for one side like this:

$x = \sqrt{A}$

Replacing we got:

$x = \sqrt{49 ft^2}= 7ft$

Then since we are interested in the how many feet of fencing does she need, we can find the perimeter given by:

$P = 4x$ and replacing we got:

$P = 4*7 ft = 28 ft$

closing probability" when driving is: a. The chance that another vehicle will be in the same place you plan to be at the same ti

mylen [45]

Answer:

The answer is "Option b".

Step-by-step explanation:

The probability of the vehicle and also another entity getting shifted more carefully together because they keep moving across a planned site. so, if going to drive is a "closing possibility." In Just 0.99 USD per month, in which users can raise your chance by either a vehicle in front of you suddenly stop and fall on your street, that's why we can say, that choice b is correct.

If ΔABC is an equilateral triangle with, AB = 2x + 17, BC = 6x - 19, AC = 4x-1, find x and the measure of each side

Soloha48 [4]

Answer:

$x=9, AB=BC=AC=35$

Step-by-step explanation:

Equilateral triangles have 3 congruent sides, so all 3 sides have the same length. Therefore, we know that $AB=BC=AC$ . We are given the lengths of all 3 sides in terms of $x$ , but we only need to set two of them equal to each other to solve for $x$ . Let's use $AB$ and $BC$ to solve for $x$ . We know that $AB=BC$ , $AB=2x+17$ , and $BC=6x-19$ . Therefore, we can write the following equation to solve for
