A middle school has an oval track with the dimensions shown. What is the distance around the track? use 3.14 for π. show your work.

10859.94

Step-by-step explanation:

To solve this, you need to know the formula for solving the area of a circle: πr²

The first thing you should do is find the area of the square: 78 x 78 = 6084

Then, we find the area of the circle. To do this, we must figure out the radius. Luckily, the problem states that the combined diameter of both half circles is 78, which means the radius is 39. Then, we can apply the formula: π39².

39² = 1521

1521 x 3.14 = 4775.94

This is the combined area of both half circles.

Finally, we have to add: 4775.94 + 6084 = 10859.94

the answer to this is:

factor 2x2+16x+24

2x2+16x+24

=2(x+2)(x+6)

answer:

2(x+2)(x+6)
