x² + 8x + 8 = 0

x² + 8x + 8 + 8 = 0 + 8

x² + 8x + 16 = 8

x² + 4x + 4x + 16 = 8

x(x) + x(4) + 4(x) + 4(4) = 8

x(x + 4) + 4(x + 4) = 8

(x + 4)(x + 4) = 8

(x + 4)² = 8

Top Company holds 90 percent of Bottom Company’s common stock. In the current year, Top reports sales of $800,000 and cost of go
dsp73

Answer:

690,000

Step-by-step explanation:

given,                        

sale of the company = $800,000              

cost of the good sold = $600,000            

percentage = \dfrac{800000-600000}{800000}

                   = 25%                          

unrealized gross profit = $100000

                        = ( $100000× 0.40 ) × 0.25

                        = $ 10,000                  

consolidated Sales = 800000 + 300,000 - 100000

                                = $ 1,000,000                    

Consolidated COGS = $600,000 + $180,000 - 100,000 + 10,000

                                  = 690,000
