Find the distance between -6 and 8
Answers: 1
Answer from: Quest
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

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
