A. 6n+3n+10= 9n+10. Jordan is 9n+10 years old.
B. 6n+9n+10= 15n+10. The total age of Prince and Jordan is 15n+10.
C. 6n-9. Kimberly is 6n-9 years old.
D. (6n+9n+10)+6n-9 = 15n+10+6n-9 = 15n+6n+10-9 = 21n+1. The total age of Prince, Jordan and Kimberly is 21n+1
E. 21•(4)+1=84+1=85. The total age of Prince, Jordan and Kimberly is 85 years.
Answer:
The range is the output.
Step-by-step explanation:
A function consists of two parts:
1. Domain - Domain is the set of all values that are inputted to a function. So, domain is set of all possible values of
.
2. Range - It is the set of all output values for given input values. It is the set of all possible values of
for given
values.
Therefore, range is the output to a function.

Answer:
the area of the triangle is 17.4cm^2
Step-by-step explanation:
Finding the area of a triangle
an isosceles triangle has two sides of equal length.
therefore to get the base of the triangle :
we need to subtract the lengths from he perimeter
30-12-12
= 6
<u>the base of the triangle is 6 cm</u>
<u></u>
<h3><u>area of a triangle</u></h3>
formula :
![\frac{1}{2} * base * height\\](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2A%20base%20%2A%20height%5C%5C)
<h3><u>getting the height of the triangle:</u></h3>
we make use of one side of the triangle , half the base. this creates a right angled triangle
we can make use of the formula
![c^{2} = a^{2} + b^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D%20%3D%20a%5E%7B2%7D%20%2B%20b%5E%7B2%7D)
were c is the hypotenuse of 12 cm
a is the adjacent of base (6/2) = 3 cm
and b is the height
![12^{2} = 3^{2} +b^{2}](https://tex.z-dn.net/?f=12%5E%7B2%7D%20%3D%203%5E%7B2%7D%20%2Bb%5E%7B2%7D)
![b^{2} = 12^{2} - 3^{2}](https://tex.z-dn.net/?f=b%5E%7B2%7D%20%3D%2012%5E%7B2%7D%20-%203%5E%7B2%7D)
![b^{2} = 135\\](https://tex.z-dn.net/?f=b%5E%7B2%7D%20%3D%20135%5C%5C)
![b = \sqrt{135}](https://tex.z-dn.net/?f=b%20%3D%20%5Csqrt%7B135%7D)
b = 11.6 cm to 3sf
<u>the height is 11.6cm.</u>
<u></u>
<em>area of the triangle is :</em>
1/2 * 3 * 11.6
<u>= 17.4 cm^2</u>
<u />
<u>the area of the triangle is 17.4cm^2</u>
