Schrank company is trying to decide how many units of merchandise to order each month. the company's policy is to have 30% of the next month's sales in inventory at the end of each month. projected sales for august, september, and october are 49,000 units, 39,000 units, and 59,000 units, respectively. how many units must be purchased in september?

27,300 units

Step-by-step explanation:

1. In order to calculate 30% of September's 39,000 sales, use 39,000x0.3, which equals 11,700 units in inventory at the end of August.

2. To find out how many units Schrank must purchase do 39,000-11,700, which 27,300 units that Schrank must purchase in September.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
