Answer:

The correct answer is A. a = 2s - b - c

Step-by-step explanation:

First you multiply 2 on both sides and you will end up with 2s = a + b + c.

Then to isolate a you would subtract both b and c from both sides of the equation as well to end up with your answer of a = 2s - b - c.

PLS HELP! ASAP!

KATRIN_1 [288]

Answer:

Your answer is C, 10.7cm

Step-by-step explanation:

The two flat sides of the figure are 3 cm, so that part of the perimeter = 6cm

3cm is the radius of what would be a whole circle. We'll calculate the circumference, then divide by 4.

Circumference = (2)(pi)(r)

C = (2)(3.14)(3)

C = 18.84

18.84/4 = 4.71

Add 4.71 to the 6 cm above, = 10.71

Let me know if you have questions about this.
