Answer:
Radius: 7.5 cm ; Diameter: 15 cm
Step-by-step explanation:
The radius of a circle is basically the middle "halfway" point and in this case, it has already been given, 7.5 cm. The diameter is the middle line of the circle and to find the diameter, you must multiply the radius by 2, which is essentially 7.5 cm*2, and this gives you a diameter of 15 cm.
Hope this helps! :D
Answer: The answer is x^2 + 4x - 3
Step-by-step explanation:
You just combine like terms, the only ones that can combine is the 6x and -4x. You just subtract them to get the answer of x^2 + 4x - 3.
Answer: n≥4
Step-by-step explanation:
If you put the value of 4 as n and multiply it by three you will get twelve which satisfies the inequality. Anything larger than 4 will also satisfy the inequality. I really hope this answer helped tell me in the comments.

Answer:
B. x = 62 because 147 – 85 = 62 and 85 + 62 = 147
Step-by-step explanation:
We are given that

Exterior angle=
We have to find the value of x.
We know that
Exterior angle=Sum of opposite interior angles of triangle
Using the property

Subtract 85 from both sides we get


Option B is true.
B. x = 62 because 147 – 85 = 62 and 85 + 62 = 147
