The2nd one is the best one
Answer:
10
Step-by-step explanation:
We know that a = 4 and b = 6, and we are trying to find the answer to both of them added, so to get a + b, we can substitue the values of a and b by their numbers. So,
a + b
Is the same as
4 + 6, which equals 10.
Therefore, the value of a+b is 10
Hope this helps :)
Answer:
Choice A. $2,392 is the correct answer
Answer: (x - 2)^2 + (y + 3)^2 = 34
Step-by-step explanation:
The basic equation for a circle is
(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the centre of the circle
Using Pythagoras we can find r^2
r^2 = (2 - -1)^2 + (-3 - -8)^2
= 3^2 + 5^2
= 34
So the circle is (x - 2)^2 + (y - -3)^2 = 34
X = 2.5, 2/5, 2 1/2. Multiplying 4 by any of these values plus 1 will result with 11
