Answer:
152 cm
Step-by-step explanation:
Once again its a square. All sides are equal.
Square root 361 to get 19.
19 x 19 = 361
4 was sewed together.
You could either add, 361+361+361+361
Or you could multiply, 361 x 4
Either way you get 1444.
You could either square root 1444 to get the side length or you could add the previous side length to itself once to get the new side length of 38.
Now you need to get perimeter.
P=4 x length
P=4 x 38
152 cm

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
Point (7, 0)
Equation y = x - 7
<u>Step 2: Find</u>
- Substitute in point [Equation]: 0 = 7 - 7
- Subtract: 0 = 0
Since 0 = 0 is true, then it would be a solution to the equation.
Answer:
The y-variable will be eliminated when adding the system of equations.
There is only one solution to the system of equations.
Step-by-step explanation:
-x + 6y = 16 (1)
8x - 6y = -2 (2)
Add the equations to eliminate y
-x + 8x = 16 +(-2)
7x = 16 -2
7x = 14
x = 14/7
x = 2
Substitute x = 2 into (1)
-x + 6y = 16 (1)
-2 + 6y = 16
6y = 16 + 2
6y = 18
y = 18/6
y = 3
(x, y) = (2, 3)
