Help me pls Analyze the system of inequalities. Tanya carns $55 per hour consulting for public advertising firms, and she earns $65 per hour consulting for private advertising firms. Combined, she can work no more than 50 hours per week. Last week, she earned less than $3,240. Let x hours for public firms, let y hours for private firms, and let the system represent the situation above

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

the eight graders whould be the answer

step-by-step explanation: could you give me 5 stars

apex says the answer is true
