Answer:
24 unit
Step-by-step explanation:
Given,
The vertices of the triangle ABC are,
A (1,1), B (7,1), and C (1,9),
By the distance formula,



Thus, the perimeter of the triangle ABC = AB + BC + CA = 6 + 10 + 8 = 24 unit
The answer is b because if you divide that’s what you get
For converting radian to degree we simply place pi as 180 degree.
So the given angle in radians =

Now can place pi = 180 degree in this angle.
So angle in degree =

So given angle in degree = -570 degree
The solution to the given equation is w = -5
<h3>Solving of expression</h3>
What is an Algebraic Expression? An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations
Given the expression below as shown;
-10w = 50
Divide both sides by -10
-10w/-10 = 50/-10
w = -5
Hence the solution to the given equation is w = -5

Answer:
-6
Step-by-step explanation:
3n = n² - 54
n² - 3n - 54 = 0
n² - 9n + 6n - 54 = 0
n(n - 9) + 6(n - 9) = 0
(n - 9)(n + 6) = 0
n = 9 , -6
