Answer:

₹1680

Step-by-step explanation:

<u>Road</u>  <u>Length (m)</u>  <u>Width (m)</u>   <u>Area (</u>m^{2}<u>)</u>

  1            80              10              800

  2           60              10               600

(800+600) = 1400 <u>(</u>m^{2}<u>)</u>

<u></u>

1400 <u>(</u>m^{2}<u>)</u>*(₹ 1.20/m) = ₹1680

Solve the equation.
Levart [38]

Answer:

x=34

Step-by-step explanation:

6 - ( x-7) ^ 1/3 = 3

Subtract 6 from each side

6-6 - ( x-7) ^ 1/3 = 3-6

- ( x-7) ^ 1/3 = -3

Divide each side by a negative

 ( x-7) ^ 1/3 = 3

Cube each side

 ( x-7) ^ 1/3 ^3 = (3)^3

x-7 = 27

Add 7 to each side

x-7+7 = 27+7

x = 34

Check

6 - ( 34-7) ^ 1/3 = 3

6 - (27^1/3 = 3

6 -3 =3

3=3

Good solution

Scilla [17]

Answer:

D. (-7)

Step-by-step explanation:

3(2 + f) = (-15)

(3 . 2) + (3 . f) = (-15)

3f = (-15) - 6

3f = (-21)

f = (-21)/3

f = (-7)
