Answer:
centre = (-5, -4)
radius = 7.42
Step-by-step explanation:
The general form for center-radius is
(x - h)² + (y - k)²= r²
Center = (h, k)
Radius = r
Rearrange the equation.
(x² + 10x) + (y² + 8y) - 14 = 0
Add 14 on both sides.
(x² + 10x) + (y² + 8y) = 14
(10/2)² = 25
(8/2)² = 16
Add 25 and 16 to both sides.
(x² + 10x + 25) + (y² + 8y + 16) = 14 + 25 + 16
Factor left side of the equation.
(x+5)² + (x+4)² = 55
(55) = (7.416198)²
(x+5)² + (x+4)² = 7.42²
The radius is 7.42.
The centre is at (-5, -4).
Answer:
-0.0936538462
Step-by-step explanation:
Start by solving the right side of the equation
1 - 2.87 = -1.87
now we have:
3 + 5.2c = -1.87
subtract 3 from both sides to get:
5.2c = -4.87
divide both sides by 5.2 to get:
-0.0936538462

Answer:
12
Step-by-step explanation:
48-6 = 42
42/7=6
6+6=12
Answer:
34.
Step-by-step explanation:
8 *6 - (4 + 10)
= 48 - 14
= 34.
K + L + M = L + M + K is an example of Commutative Property of Addition
Commutative Property of Addition means the order of the terms doesn't matter. You can still get the same answer on both sides of the equation even though the order of numbers are not the same.
Example:
5 + 3 + 7 = 3 + 7 + 5
15 = 15
As you can see above, the sum of the left side of the equation is the same as the sum of the right side of the equation which is 15.
