Answer:

7.5 meters

Step-by-step explanation:

As with many quadrilaterals, pairs of sides have the same length, so the perimeter is twice the sum of two of the sides.

In a kite, generally, opposite sides have different lengths, so the perimeter is twice the sum of the lengths of opposite sides. That is

51 m = 2(18m + side opposite)

15 m = 2 × (side opposite)

7.5 m = side opposite

_____

Comment on side lengths

In a rectangle or parallelogram, the perimeter is twice the sum of adjacent sides. A kite is different in that adjacent sides may be the same length. If the kite is not a rhombus, opposite sides are always different lengths.

$\frac{ {a}^{2} - {b}^{2} }{a + b} \\ \frac{(a - b)(a + b)}{a + b}$

Therefore, the answer is

$a - b$

Solve the equation for x. 25x = 275 x =

Sliva [168]

Answer:

x = 11

Step-by-step explanation:

So the equation is 25x = 275. In order for us to find out what x is we need to get rid of 25 that is next to x, so we are going to have to divide 25x by 25. What you do to one side you do to the other so the equation will look like this:

25x/ 25 = 275/ 25

25x/25 = x

275/25 = 11

so x = 11

79, 79, 91, 91, 91, 91, 98, 98, 118, 130, what is the mean median and mode?

Rus_ich [418]

To get the mean you add the numbers and divide by how many numbers there are and then you would get: 784 divided by 10 which would be 78.4 for the mean
