The figure of the kite shown in the figure is a quadrilateral because it has four sides. The lengths of each side is expressed as a function of x and y. In order to determine the values of x and y, you make use of the short lines that mark the sides. These are symbols of congruency. If two sides are equal, you mark them both with the same symbol. So for the figure above, side NM = side LM and side KL = side KN. Therefore, we equate them as follows:
NM = LM
2x + 6 = 3x - 1
3x - 2x = 6 +1
x = 7
KL = KN
2y + 5 = y + 10
2y-y = 10 - 5
y = 5
So, we know that the values are x=7 and y=5. We use this to know the actual values of sides KN and NM.
KN = y + 10
KN = 5 + 10
KN = 15
NM = 2x + 6
NM = 2(7) + 6
NM = 20

<h2>30</h2>
Step-by-step explanation:
<h3>to understand the steps</h3><h3>you need to know about:</h3>
- system of linear equation
- word problems
- PEMDAS
first step
let's create the equation word problem
<h3>my mother's current age is four times the sum of the ages of my two sisters. After 5 years, my mother's age will be double the sum of the ages of my two sisters. What is the current age of my mother? (imaginary problem)</h3>
let's solve
let my mother's and sister's age be x and y respectively
according to the first condition,x=4y....(I)
according to the 2nd condition,x+5=2(y+5×2).....(ii)
so the system of linear equations is
x=4y
x+5=2(y+5×2)
gets from the second equation
x+5=2(y+10)
x+5=2y+20
4y+5=2y+20 (as x=4y)
2y=15
y=7.5
so the age of mother is
x=4.(7.5)
x=30
<span>3 + 3 x 3 - 3 + 3
Multiply 3 by 3
3 + 9 - 3 + 3
Add 3 to 9
12 - 3 + 3
Subtract 3 from 12
9 + 3
Add
Final Answer: B. 12</span>
