A chimney is to be built with bricks and it must be 4 metres high. Each layer of bricks in the chimney is 8 centimetres high and 52 bricks are used to make one layer.
a) How many bricks would the bricklayer need to make this chimney?
b) If each brick cost $1.25, what is the cost of all the bricks?

Help, please​

$35.59 in pounds

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
