A frog sitting on a stump 4 feet high hops off and lands on the ground during her leave the frogs height H and feet is given by the equation H equals -0.5 B squared plus D +4, we’re D is the total horizontal distance and which feet from the base of the stump. How far from the stump that the frog land?

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 height of the surface increases from the center out to the sides of the road

it is c!
