Mr. lewis sees a red light ahead and applies the brakes on his car. the car travels 300.5 feet before coming to a stop. for each foot the car travels during this time, its speed changes by -0.2 miles per hour. what is the total change in the car's speed during that time? ( answer as soon as possible ) a. -36.5 b. -60.1 c. -60.10 d. 36.5

multiply distance by change in speed:

300.5 feet x -0.2 mph

300.5 * -0.2 = -60.1 change in speed

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
