A red horse and a black horse raced on a 1-mile-long circular racetrack. The red horse completed the race in 120 seconds, and the black horse completed the race in 150 seconds. Which choice correctly describes the speed of the horses?
O A. Only the red horse ran at a constant speed.
OB. Only the black horse ran at a constant speed.
C. The red horse's average speed was greater than the black horse's average speed.
O D. The black horse's average speed was greater than the red horse's average speed.

idk what the heck he answer is, i’m just putting this here so i finish my account

agree

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²

it is 32.5

i hope i could u.
