Evaluate c= 2 a r, for r= 8.
c=10,
c = 16
c= 28.7
c= 16

Second Option

Step-by-step explanation:

We are evaluating aarco lengths

The formula for the arc length is:

We want to know what is the arc length for a radius of r = 8

Then we substitute r = 8 in the equation and solve

The correct answer is the second option

Correct choice is .

Step-by-step explanation:

Given equation is .

Now we need to find the value of C using given equation and .

To find that, we just need to plug into and simplify.

Hence correct choice is .

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
