82.5 i believe because the radius is half of the diameter.
This is an example of the commutative property of addition. This is because changing the addends or factor's does not affect the sum or product.
Answer:
addition property of equality
inverse property of multiplication
Step-by-step explanation:
7y − 15 = −29
Add 15 to each side using the addition property of equality
7y -15+15 = -29+15
7y = -14
Divide each side by 7 using the inverse property of multiplication
7y/7 = -14/7
y =2
Step-by-step explanation:
The function is as follows :

We need to find the zeroes of the function in the simplest radical form.The zero of the above function is given by :

Here,
b = 5
a = 1
c = 5
So,

Hence, the correct option is (c).
