Answer:
3.5
Step-by-step explanation:
11.5 - 2.5 = 9
9 - 5.5 = 3.5
and scalene triange means none of the 3 sides are equal...
3.5 does not equal 5.5 or 2.5
Answer:
-x > -5
Step-by-step explanation:
Let's start with a positive number less than 5.
4<5
likewise when applied to -x> -5
-4>-5

Answer:
d. AB = 54
Step-by-step explanation:
The triangle is isosceles, so AB = AC.
(4x +6) = (5x -6)
12 = x . . . . . . . . . . . . add 6-4x to both sides
Then the length of AB is ...
AB = 4x +6 = 4(12) +6 = 48 +6
AB = 54
Answer:
The answer is (C)
The equation of the circle is (x + 4)² + (y - 6)² = 81
Step-by-step explanation:
* To find the equation of the circle you need to know
the center of the circle and the length of its radius
* The rule of the equation of the circle is:
(x - h)² + (y - k)² = r²
Where x and y is a general point on the circle,
h and k are the coordinates of the center of the circle
and r is the radius of the circle
∵ The center of the circle is (-4 , 6)
∵ The radius of the circle is 9
∴ (x - -4)² + (y - 6)² = 9²
∴ ( x + 4)² + (y - 6)² = 81
∴ The answer is (C)
