Answer:

(3^2•2^2x^2y^4)

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

 ((3xy3 • 2) • xy) • 6

Step  2  :

Equation at the end of step  2  :

 ((3•2xy3) • xy) • 6

Step  3  :

Multiplying exponents :

3.1    31  multiplied by  31   = 3(1 + 1) = 32

Multiplying exponents :

3.2    21  multiplied by  21   = 2(1 + 1) = 22

Final result :

 (32•22x2y4)

When 2 pieces of rope are placed end to end they measure 40 meters in length when the 2 pieces are laid side by side one is 10 m
poizon [28]

Answer:

15 meters and 25 meters long

Step-by-step explanation:

<em>There are 2 pieces of rope</em>.

Total length of both---> 40 meters

Length of piece 1 ------> x

Length of piece 2 -----> x + 10

<em>Find the value of x.</em>

<em>Form an equation ----> Length of piece 1 + length of piece 2 = total length</em>

x + (x + 10) = 40

2x + 10 = 40

2x = 30

x = 15

Length of piece 1 --> x ---> 15

Length of piece 2 --> x + 10 ----> 15 + 10 = 25

Therefore, one piece is 15 meters long and the other piece is 25 meters long.

Find the area and circumference.
saveliy_v [14]

Answer:

  • area ≈ 176.7 cm²
  • circumference ≈ 47.1 cm

Step-by-step explanation:

The radius is half the diameter, so is ...

  r = d/2 = 15 cm/2 = 7.5 cm

The area formula is ...

  A = πr²

Filling in the radius, we have ...

  A = π·(7.5 cm)² = 56.25π cm² ≈ 176.7 cm² . . . area

__

The circumference formula is ...

  C = πd

Filling in the diameter, we have ...

  C = π·(15 cm) = 15π cm ≈ 47.1 cm . . . circumference
