Find 1 round
--------------------------------------------------

1 round of the circle = πD
1 round of the circle = π(2x4)
1 round of the circle =8π

--------------------------------------------------
Find 10 rounds
--------------------------------------------------

10 round of the circle = 8π x 10 
10 round of the circle = 80π
10 round of the circle = 251.33 m

251.33m. First find the distance around one circle then times by ten for all the circles.
Circumference of each circle=2x(pi)xr
=2(Pi)x10
=25.13
For ten circles=25.13x10
=251.33

Use Long Division to answer number 4. Please show all work!​
skelet666 [1.2K]

Answer:

2x² + 3x + 4 + (17x + 9) / (x² − 4)

Step-by-step explanation:

Start by setting up the division.  Make sure to write all the coefficients, even the zero ones.

x² + 0x − 4 | 2x⁴ + 3x³ − 4x² + 5x − 7

Start by dividing the first term of the dividend (2x⁴) by the first term of the divisor (x²).  That's 2x²; it'll be the first term in quotient.  Multiply the divisor by 2x²:

2x⁴ + 0x³ − 8x²

Subtract that from the first three terms of the dividend:

3x³ + 4x²

Drop down the next term from the dividend, and start the process all over again.

3x³ + 4x² + 5x

When you finish, the quotient will be 2x² + 3x + 4, and the remainder will be 17x + 9.
