The perfect winter coat is on sale for 40% off the original price is 105 what is the sale of the coat

$63

Step-by-step explanation:

The coat is originally priced at $105. During the sale the price would by 40% off which means you pay 60% of the original price. We can find this by multiplying by the percent 60 converted into a decimal.

105(0.60)=63

The sale price at the sale is $63.

where is abdul's work? don't see that anywhere posted : /

step-by-step explanation:

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
