Answer:

Board 1 = 1.2m

Board 2 = 2.4m

Board 3 = 3.6m

Step-by-step explanation:

Board 1 = x

Board 2 = 2x

Board 3 = 3x
x + 2x + 3x = 6x

7.2 /6 = 1.2

Board 1 = 1.2

Board 2 = 2 (1.2) = 2.4

Board 3 = 3 (1.2) = 3.6

Solve the following equation: <br><br> x^3 -168 = [24(x-2)] / 2<br><br> PLEASE REPLY ASAP
Nataly_w [17]
Hi Larry

x^3 - 168 = [ 24(x-2)] / 2
x^3 - 168 = (24x - 48)/2
x^3 - 168 = 12x - 24
Subtract 12x - 24 to both sides
x^3 - 168 - (12x - 24) = 12xx - 24 - (12x - 24)
x^3 - 12x - 144 = 0
Now, factor the left sides
(x - 6)(x^2 + 6x + 24) = 0
Set factors equal to 0
x - 6 = 0 or x^2 + 6x + 24 = 0
x = 0 + 6 or x^2 + 6x + 24 - 0
x = 6
Answer : X = 6

Good luck !
