The american antelope (pronghorn) and thw wildebeest are amoung the fastest mammals on tje planet, particularly at running long distances. The maximum recorded speed for the antelope is 88.5 km/h, which it can substain for nearly one kilometer. On the other hand, the distance, d, in kilometers that the wildebeest can run in t hours is given by the equation d = 80.5t. assuming both animals are running at constant speeds, which animal can run faster

what is all that apply?

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction

step-by-step explanation:

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
