Answer:

D. None of the choices are correct.

Step-by-step explanation:

If B is the midpoint of AC, then that means that AB is congruent to BC. Because this is true, you can set 8x + 4 and 10x - 8 equal.

8x + 4 = 10x - 8

Now just solve for x. Subtract 8x from both sides and add 8 to both sides.

4 = 2x - 8

12 = 2x

Then divide by 2.

6 = x

Another way to do this problem is to set up the same equation, but instead of solving it, plug in answer choices A, B, and C independently of each other. Then simplify to see if those are right. You'll find out that none of them are.

Find the perimeter of the figure to the nearest hundredth. Ps: it is not 30

frutty [35]

Answer:

Perimeter = 36.8 ft

Step-by-step explanation:

Step 1: Add the straight sides together

3+3+3+3+3+3 = 18 ft

Step 2: Find the perimeter of the semi-circles

The formula for the perimeter of semi-circle: 1/2 π × d

Diameter = 12 - 3 - 3 = 6, because the whole length is 12 minus the 6 ft of other stuff.

Now, 1/2π * 6 = 9.4 ft

But, there are two semi-circles so it will be 9.4 + 9.4 = 18.8 ft

Step 3: Add all of them

18 + 18.8 = 36.8 ft
