Answer:
First Step: separate x^2 from -16
Second Step: add -16/25 to the other side.
Step-by-step explanation:
x^2 - 16/25 = 0
^^ this might be easier if you separate x^2 and -16
<em>First Step-</em>
so rewrite the problem as x^2/25 -16/25 = 0
then...
<em>Second Step-</em>
add -16/25 to the other side. This makes it: x^2/25 = 16/25
<em>Continuation-</em>
Now, you can multiply 25 on both sides to cancel it out.
so you have x^2 = -16

Answer:
39,51
Step-by-step explanation:
Complementary angles add to 90 degrees
Let one angle be x
The other angle is x+12
x+ x+12 = 90
Combine like terms
2x+12 = 90
Subtract 12 from each side
2x+12-12 = 90-12
2x = 78
Divide each side by 2
2x/2 = 78/2
x =39
The other angle is 39+12 =51
You would find the radius by halving the diameter. Then you use the equation

and you get about 28.2 meters.
