Answer:
312
Step-by-step explanation: 936/3=312
Answer:
A. x=5,y=6
Step-by-step explanation:
Add y to both sides of the equation.
x=−1+y
x−3y=−13
Replace all occurrences of x with −1+y in each equation.
−1−2y=−13
x=−1+y
Solve for y in the first equation.
y=6
x=−1+y
Replace all occurrences of y with 6 in each equation.
x=5
y=6
The solution to the system is the complete set of ordered pairs that are valid solutions.
(5,6)
The result can be shown in multiple forms. Equation Form: x=5,y=6
Perimeter is the sum of the length of the sides used to make the given figure. The perimeter of the regular octagon is 8√58 units.
<h3>What is the perimeter?</h3>
Perimeter is the sum of the length of the sides used to make the given figure.
For a regular octagon, the length of each side of the octagon is the same. Therefore, the length of a single side of the octagon is,
Length of the side of the octagon = √[(-4-3)² + (0 + 3)²] = √58
Now, the perimeter of the octagon is 8 times of√58.
Perimeter = 8 ×√58 = 8√58
Hence, the perimeter of the regular octagon is 8√58 units.
