Answer:
12cm³
Step-by-step explanation:
1/2x2x6x2=12cm³
Since you are solving for a, you want to have a on one side of the equation and the other terms on another side of the equation. It would be easiest to have all the terms with a on the left side of the equation, so that is what we will do.
Subtract 9a from both sides to get a on the left side of the equation.
5 + 5a = -5
Subtract 5 from both sides of the equation to isolate the term with a.
5a = -10
Divide both sides of the equation by 5 to solve for a.
a = -2
Answer:
(x +9) ^2 + (y +7)^2 = 289
Step-by-step explanation:
We know the equation of a circle can be written as
(x-h) ^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
We are given the diameter so we can find the radius
r = d/2 = 34/2 = 17
(x- -9) ^2 + (y- -7)^2 = 17^2
(x +9) ^2 + (y +7)^2 = 17^2
(x +9) ^2 + (y +7)^2 = 289
(-8,2) (4,2)
