Hurry the johnson family is taking a car trip. they are driving at an average speed of 60 miles per hour. the graph shows their distance traveled over time. what does the point (5, 300) represent in this situation? a) the johnson family will travel 300 miles in 5 hours. b) the johnson family will finish their trip in 5 hours. c) the johnson family drives 5 miles per hour for 300 miles. d) the johnson family vacation destination is 300 miles away.

A) the Johnson family will travel 300 miles in 5 hours

Assuming 5, represents the amount of hours & 300 representing miles

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
