Please please i need help

Step-by-step explanation:

here's your solution

=> time for Bettinia = 3.8 hrs

=> speed of her = 56 mph

=> distance covered by her = 3.8*56 = 212.8m

=> time for wills = 4.1 hrs

=> speed of wills = 52 mph

=> distance = 4.1 * 52 = 213.2m

=> wills covered more distance = 0.4 m

hope it helps

the correct answer is the second option

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
