<span>It's 628 feet.
She rode the circumference of a circle.
Formula is (2xR)x3.14 (pi)
2 x R = 200
200 x 3.14 = 628</span><span>

$650. You start with finding how many square feet the floor and the tiles are. 40x50=2000 square feet for the floor and 2x2=4 square feet for the tile. You then take 2000/4=500 to get the amount of tiles that you will need. After that, you take 500/10=50 to get the number of packages you will need. The final step is taking 50x13=$650 to get the total cost
Answer: 16x+3+x214
Step-by-step explanation:
Multiply 2 and 2 to get 4.
4+16x+x214−1
Subtract 1 from 4 to get 3.
3+16x+x214
To add or subtract expressions, expand them to make their denominators the same. Multiply 3+16x times x2x2.
x2(3+16x)x2+x214
Since x2(3+16x)x2 and x214 have the same denominator, add them by adding their numerators.
x2(3+16x)x2+14
Do the multiplications in (3+16x)x2+14.
x23x2+16x3+14
Answer for this system: (-1, 4)
