Eloise wants to make 3 cinder block gardens. A cinderblock has the dimensions 2/3' x 2/3' x 1 1/3'. Garden A is 48" x 48" x 16". Gardens B and C are the same sizes. If B and C were put together and formed 1 giant garden its dimensions would be 96" x 32" x 24". How many cinderblocks does she need to buy?

Eloise procedure

((-2x+1) ^1/2)-3=xok

((-2x+1) ^1/2)-3+3=x+3ok

((-2x+1) ^1/2)=x+3ok

((-2x+1-1) ^1/2)=x+3-1>this is the error

 the correct is ((-2x+1) ^1/2)-1=x+3-1

 I solve correctly

((-2x+1) ^1/2)=x+3((-2x+1) ^1/2) ^2=(x+3) ^2

(-2x+1) =(x+3) ^2

-2x+1=x^2+6x+9

 -x^2+8x+8=0

solving the quadratic equation

x1=-6.828

x2=-1.172

 the solution is x=-1.172 

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
